Let’s assume the cost of apples is x dollars.

She paid $3 less for oranges than she did for apples (Given)


According to the given information, the cost of oranges would be x – $3.

But, the total cost of apples and oranges = $10.

Cost of apples=x

Cost of oranges= x-3

We can write this as an equation:


x (x – $3) = $10

Solving for x:

2x – $3 = $10

2x = $13

x = $6.50

So, Sarah spent $6.50 on apples and $6.50 – $3 = $3.50 on oranges.

Therefore, Sarah spent $3.50 on oranges.
