Powered by Question2AnswerAnswered: the cost for a 100-seater bus for a field trip is $45,525 , if 80 seats are then sold at 292.5 and a further 10 seats at 15% discount on the initial price. Calculate the total profit made in $

<p style="text-align:justify"><span style="font-family:.sfuitext; font-size:17pt">80 seats sell for $23400.</span></p>
<p style="text-align:justify"><span style="font-family:.sfuitext; font-size:17pt">15% reduction makes the 10 seats each cost 0.85×292.50=$248.625 and the sale of 10 seats would be $2486.25 or $2486.30 depending on whether the cost is rounded to the nearest cent. So 90 seats out of 100 will be occupied.</span></p>
<p style="text-align:justify"><span style="font-family:.sfuitext; font-size:17pt">Seat sales come to 23400+2486.25=$25886.25.</span></p>
<p style="text-align:justify"><span style="font-family:.sfuitext; font-size:17pt">Profit is 25886.25-45525=-$19638.75 or -$19638.70.</span></p>
<p style="text-align:justify"><span style="font-family:.sfuitext; font-size:17pt">This is a loss because the cost of the bus is higher than the revenue from seat sales. (To make a profit, the average price for a seat must be more than $455.25 and 100 seats would need to be sold.)</span></p>Word Problem Answershttps://www.mathhomeworkanswers.org/267397/seater-seats-further-discount-initial-calculate-total-profit?show=267450#a267450Wed, 23 Oct 2019 01:09:26 +0000Answered: what are the common multipuls of 3,7,& 8

(Round your answer to one decimal place.)
https://www.mathhomeworkanswers.org/267189/expected-probability-winning-profit-answer-decimal-place?show=267215#a267215
<p style="text-align: justify;"><span style="font-family:.sfuitext; font-size:17pt">If we take the general case where a wager W is placed on a value V to be won where the probability of winning is p, then the expected value is made up of the value of winning=V-W (forfeiting the wager but gaining the prize) combined with the probability p of winning=(V-W)p; and the loss of wager combined with the probability 1-p of losing=W(1-p).</span></p>
<p style="text-align: justify;"><span style="font-family:.sfuitext; font-size:17pt">The expected value, the sum of the products of value and probability of each outcome (winning and losing), is the difference between these: (V-W)p-W(1-p)=Vp-Wp-W+Wp=Vp-W, because loss is a negative value.</span></p>
<p style="text-align: justify;"><span style="font-family:.sfuitext; font-size:17pt">If p=⅛ as given in the question, then the expected value is ⅛V-W. The expected value per wager is (⅛V-W)/W=⅛V/W-1.</span></p>
<p style="text-align: justify;"><span style="font-family:.sfuitext; font-size:17pt">It’s not clear what is meant by profit=4W: If the profit is the same as Vp-W (expected value)=4W then V=40W, and the expected value per wager is 4;</span></p>
<p style="text-align: justify;"><span style="font-family:.sfuitext; font-size:17pt">if the the profit is the value of winning=V-W, then V-W=4W, so V=5W, making V/W=5, and the expected value per wager is ⅝-1=-⅜=-0.375 or -0.4 to 1 decimal place.</span></p>Word Problem Answershttps://www.mathhomeworkanswers.org/267189/expected-probability-winning-profit-answer-decimal-place?show=267215#a267215Fri, 18 Oct 2019 14:14:54 +0000Answered: adrian ran 8.547 km in 1.5 hours how many kn did he run in 1 hour

<ol>
<li style="text-align:justify"><span style="font-size:20px">f(n)=2n+80, because if n=0 (no pizzas) the other charges would still apply. For every pizza the cost increases by $2, so the cost increases by 2n dollars if n pizzas are made.</span></li>
<li style="text-align:justify"><span style="font-size:20px">When n=20, f(20)=40+80=$120. </span></li>
<li style="text-align:justify"><span style="font-size:20px">If f(n)=200, 200=2n+80, 2n=200-80=120, so n=60. The cost of 60 pizzas is $200.</span></li>

<li style="text-align:justify"><span style="font-size:20px">R(n)=8n. When n=1, a single pizza is divided into 8 slices each costing $1. So n pizzas sell for 8n dollars.</span></li>
<li style="text-align:justify"><span style="font-size:20px">When n=20, R(20)=$160, so you would receive $160 if you sold 160 slices at 8 $1 slices per pizza, 20 whole pizzas.</span></li>

If 14 pizzas were made, that would produce 112 slices, sold for $112. The cost of making 14 pizzas would be $108, so break even would be when 108 slices had been sold.

<li style="text-align:justify"><span style="font-size:20px">To make a profit of $100, P(n)=100=6n-80, 6n=180, n=30. So 30 pizzas would have to be made.</span></li>

https://www.mathhomeworkanswers.org/266205/how-many-18-inches-are-in-18-ft?show=266216#a266216
<p style="text-align: justify;"><span style="font-family:.sfuitext; font-size:17pt">12, because there are 12 inches in 1 foot.</span></p>
<p style="text-align: justify;"> </p>
<p style="text-align: justify;"><span style="font-family:.sfuitext; font-size:17pt">But, to answer how many slabs, we need to find how many slabs fit 14 feet.</span></p>
<p style="text-align: justify;"><span style="font-family:.sfuitext; font-size:17pt">18 in = 1.5 ft, so we need 14/1.5=9⅓ slabs. To fill an area 18 ft (12 slabs) by 9×1.5=13.5 ft (9 slabs) we set up a 12×9 slab array. 9×12=108 slabs.</span></p>
<p style="text-align: justify;"><span style="font-family:.sfuitext; font-size:17pt">But we need to make up from 13.5 to 14 ft. That’s 6 inches to fill, which is ⅓ slab. If 4 slabs are cut into three pieces 6 inches wide, we end up with 12 pieces 6 inches wide—enough to fill the whole 18 feet and take the width up to 14 feet. That makes the total number of slabs 108+4=112 slabs.</span></p>
