Question

Rick started his retirement account with 5,000 when he was 23. When he retired at age 65, he had 2.2 x 10⁶ dollars in his retirement account. How many times greater was his account when he retired?

A. 4.4 x 10² times greater
B. 4.4 x 20⁴ times greater
C. 2.8 x 10³ times greater
D. 2.8 x 10² times greater

Answer 1

Rick's retirement account was 4.4 x 10^2 times greater when he retired.

To find out how many times greater Rick's retirement account was when he retired, we can divide the final amount in his account by the initial amount he started with. Rick started with $5,000 and ended up with 2.2 x 106 dollars, which can be written as 2.2 x 106. So, the calculation is:

2.2 x 106 / (5,000) = 4.4 x 102

Therefore, Rick's retirement account was 4.4 x 102 times greater when he retired.
