Question

At a fruit stand , apples sell for $ 1.20 per pound . One week , the stand sold $600 worth of apples and pears . The equation below describes the situation , where A is the number of pounds of apples and P is the number of pounds of pears . 0.8a + 1.2p = 600 Which graph represents the equation?

Answer 1

we can calculate two points in order to know what graph corresponds to the equation

when a=0

1.2p=600

p=600/1.2

p=500

the point is (0,500) red point

when b=0

0.8a=600

a=600/0.8

a=750

the point is (750,0) green point

the answer is B
