Answer:
Each apple cost $1.12
Explanation:
The total amount spent is the sum of the amounts spent on oranges added to the amount spent on apples. Given that Ben bought 3 oranges for 89 cents each, amount spent on oranges
= 3 * $0.89
= $2.67
If Ben bought 4 apples for x dollars each, amount spent on apples
= 4x
Total amount spent is $7.15
2.67 + 4x = 7.15
4x = 7.15 - 2.67
4x = 4.48
x = $1.12
