Question

In the next 10 month,Colin wants to save $900 for his vacation.He plans to save $75 each of the first 8 months. How much must he save each of the last 2 months in order to meet his goal if he saves the same amount each month ?

Answer 1

He saves $75 for 8 months for a total of 75 x 8 = $600

He wants to save $900

So he needs 900 - 600 = 300 more.

This means he needs to save 300 / 2 months = $150 per month.
