Answer: the inequality statement is
62.12 + x ≤ 75
Explanation:
Let x represent the cost of the present that she needs to buy for her brother.
She bought a shirt for her dad for $21.95 a necklace for her mother for $23.42 and a cd for her sister for $16.75. The total cost of all the presents that she already bought would be
21.95 + 23.42 + 16.75 = 62.12
Trinity had $75 to buy presents for her family for the holidays and she still has to buy a present for brother. Therefore, the inequality representing the situation would be
62.12 + x ≤ 75
