Answer: Anna bought 10 oranges
Step-by-step explanation:
Let x represent the number of apples that Emma bought.
Let y represent the number of oranges that Anna bought.
Emma and Anna went to the market to buy 25 fruits. This means that
x + y = 25
Emma got a few apples that cost $2 each, and Anna bought some oranges which cost $3 each. If their combined total is $60, it means that
2x + 3y = 60 - - - - - - - - - -1
Substituting x = 25 - y into equation 1, it becomes
2(25 - y) + 3y = 60
50 - 2y + 3y = 60
- 2y + 3y = 60 - 50
y = 10
x = 25 - y = 25 - 10
x = 15
