Question

Mrs. Steward needs to save (4.2 X 10^6) dollars for her children's college education. If she can save (1.4 X 10^2) each month, how many months will it take her to save? How many years?

Answer 1

Answer: 30,000 months or 2,500 years

She'd better start saving more haha.

Explanation:

`Goal=4.2x10^6\\Savings/month=1.4x10^2`

`(4.2x10^6)/(1.4x10^2) =((4.2)/(1.4))x10^(^6^-^2^)=(3)x10^4=3x10^4 =30000 months=(30000)/(12)=2500years`
