Answer:
Apple: $2.50
Orange: $1.75
Explanation:
Let A represent apples and Y represent Orange
We have equations
9A + 6Y = $33
18A + 20 Y = $80
Let's find out the cost of oranges first. Multiply the first equation by -2
-18A - 12Y = $-66
18A + 20 Y = $80
8Y = $14
Y = $1.75
Now let's put 1.75 back in the Y to find the cost of apple
18A + 20(1.75) = $80
18A + 35 = $80
18A = $45
A = $2.50
