Question

Diego started a savings account with $120. Every month, he deposits $15 into the account. He wants to know

the number of months, m, until his account has a balance of at least $200. Write an inequality to represent
this situation.

Answer 1

The inequality 15m + 120 ≥ 200 represents the situation.

Explanation:

Given that:

Diego started savings account with $120.

Amount deposited each month = $15

Number of months = m

The least balance he wants to have = $200

Amount deposited each month * No. of months + Amount deposited at start ≥ Least amount of balance

15*m + 120 ≥ 200

15m + 120 ≥ 200

Hence,

The inequality 15m + 120 ≥ 200 represents the situation.
