At the beginning of the year, Jason had $120 in his savings account. Each month, he added $15 to his account.
Write an equation for the amount of money \( A \) in Jason's savings account each month. Then use the equation to find the amount of money in his account at the end of the year.
\[
\text{Month:} \quad 1 \quad 2 \quad 3 \quad \ldots \quad m
\]
\[
\text{Amount:} \quad \$135 \quad \$150 \quad \$165 \quad \ldots \quad \$?
\]
Answer (3)
Month 1: $135 Month 2: $135 + $15 = $150 Month 3: $150 + $15 = $165
Month 12: $120 + 12 * $15 = $120 + $180 = $300
Answer: Jason had $300 in his account at the end of the year.
The equation that represents the amount of money Jason has in his account each month is A = 120 + 15M. By plugging in 12 for M to represent the 12 months in a year, we find that Jason has $300 in his account at the end of the year. ;
The equation for the amount of money in Jason's savings account each month is A = 120 + 15 m . At the end of the year, after substituting m = 12 , Jason will have $300 in his account.
