Step-by-step explanation:

let the cost of apples be x and grapes be y

from question

2x+y=240(equation 1)

after a month…

4x+2y=500(equation 2)

from 1(write x in terms of y)

x=(240-y)/2

from 2(write x in terms of y)

x=(500-2y)/4

from 1 sub y=0

we get (240-0)/2=120

from 1 sub y=2

we get(240-2)/2=119

from 1 the points are

(0,120) and (2,119)

from 2 sub y= 10

[500-2(10)]/4=120

from 2 sub y=50

[500-2(50)]/4=100

from 2 the points are

(10,120) and (50,100)

plot these point on the graph.

NOTE: you can substitute any numbers to y but the answer should be in whole number and not in fraction…
