Question

9 apples and 6 oranges cost $33. 18 apples and 20 oranges cost $80. how much does one apple and one orange cost?

Answer 1

Answer:2 50

Explanation:

Answer 2

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
