# The cost of 4 bananas and 4 oranges is $36.

The cost of 4 bananas and 4 oranges is $36. The cost of 2 bananas and 5 oranges is $33. What is the cost of 1 orange?

## Answer/Solution

5

### Steps/Work

Let the cost of 1 banana = x, let the cost of 1 orange = y

4x + 4y = 36

x = (36 - 4y)/4

x = 9 - y

Again,

2x + 5y = 33

2(9 - y) + 5y = 33

18 - 2y + 5y = 33

3y = 15

y = 5

Answer: B

4x + 4y = 36

x = (36 - 4y)/4

x = 9 - y

Again,

2x + 5y = 33

2(9 - y) + 5y = 33

18 - 2y + 5y = 33

3y = 15

y = 5

Answer: B
