Answer: the maximum number that she can buy is 2 bags of fruits.
Explanation:
Let b represent the number of bags of fruit that Harper wants to buy.
She is going to buy bags of fruit that cost $4.75 each and one box of crackers that costs $3.50. This means that the total cost of buying x bags of fruits and one box of crackers is
4.75x + 3.5
Harper has $15.00 to spend at the grocery store. Therefore, the inequality that models this situation is
4.75x + 3.5 ≤ 15
4.75x ≤ 15 - 3.5
4.75x ≤ 11.5
x ≤ 11.5/4.75
x ≤ 2.4
Since the number of number of bags of fruit cannot be a fraction, the the maximum number that she can buy is 2
