Solve the following real-world problem: Destiny opens a checking account with $100 and then deposits $27 each week. How many weeks will it take her account to reach $343?

Question

A. 16.4 weeks
B. 12.7 weeks
C. 9 weeks
D. 3.16 weeks

Answer 1

To solve this problem, we can set up an equation to represent Destiny's total amount in her checking account after x weeks.

Total amount = Initial deposit + (Weekly deposit * Number of weeks)

Total amount = $100 + ($27 * x)

We want to find out how many weeks it will take for her account to reach $343.

$343 = $100 + ($27 * x)

$343 = $100 + $27x

$243 = $27x

x = 9

Therefore, it will take Destiny 9 weeks for her account to reach $343.

C. 9 weeks
