graph three combinations using plants $25 and shrubs $20 to = $300

Question

graphing from a word problem

p is $25   s is $20  T is $300

graph the equation and use te graph to determine three different cominations of plants and surbs tat total $300

Answer 1

25p+20s=300 where p=number of plants and s=number of shrubs.

This can be reduced to 5p+4s=60 by dividing through by 5. In the graph below the vertical axis p is the horizontal axis and s the vertical axis.

4 points are shown: C(0,15), A(4,10), B(8,5), D(12,0).

A: 4 plants, 10 shrubs: 25×4+20×10=100+200=$300;

B: 8 plants, 5 shrubs: 25×8+20×5=200+100=$300;

D: 12 plants, no shrubs: 25×12=$300.
