inequalities

Question

a cell phone company has offered you two different rates. The first rate is $35 per month and 5 cents per phone call (time does not matter). The second offer is $55 per month and 2 cents per call. Set up the inequality to model this problem and find where it is less expensive to go with the second plan.

Answer 1

first scheme's cost is 35+0.05t (where t is number of calls)

second is 55 + 0.02t

for second plan to be less expensive

it's 55 + 0.02t < 35 + 0.05 t

or  0.03t > 20

t > 666

in other words, if you make more than 666 calls the second plan will cost you less

Answer 2

What are the steps of the order of operations? Why is it important that you follow the steps rather than solve the problem from left to right?

 

- Write an expression for your classmates to simplify using at least three of the following:

o Groupings: Parenthesis, brackets, or braces
o Exponents
o Multiplication or division
o Addition or subtraction

 

- Consider participating in the discussion by simplifying a classmate’s expression, showing how the expression would be incorrectly simplified if computed from left to right, or challenging the class with a complicated expression. Respond to your initial post and provide your classmates with the answer to your expression. 

 

Answer 3

operatio in math first do any calculation tat are inside parenthese and take care of exponents and roots, next, perform all multiplication and divisions left to right then do all addition and subtration left to right.
