Answer:
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...
hope it is helpful...
