Question 1168289: Sarah spent a total of $10 on oranges and apples at the supermarket. If she paid $3 less for oranges than she did for apples, how much did Sarah spend on oranges? Found 2 solutions by ikleyn, greenestamps:Answer by ikleyn(52776) (Show Source):
oranges = x dollars
apples = x+3 dollars
An equation is
Oranges + Apples = 10 dollars, or
x + (x+3) = 10
2x = 10-3
2x = 7
x = 7/2 = 3.5
ANSWER. Sara spent $3.50 for oranges.
x = dollars spent on oranges
x+3 = dollars spent on apples ($3 more than what was spent on oranges)
The total spent was $10:
(x)+(x+3) = 10
