Question

Amy currently has $140 in her savings account. She plans to make weekly deposits into the account of $18. She wants to save at least y dollars before withdrawing any money. If x represents the number of weeks of deposits, which of the following inequalities represents this situation? A. $18 + $140x > y B. $140 + $18x > y C. $18 + $140x < y D. $140 + $18x < y

Answer 1

The amount in Amy's savings account will increase by $18 each week, so after x weeks, she will have saved $18x. Adding this amount to her initial savings of $140 gives a total savings of $140 + $18x.

Amy wants to save at least y dollars before withdrawing any money, which means that she must have more than y dollars in her account. Therefore, the inequality should involve a greater than sign.

The correct answer is (B) $140 + $18x > y.
