In the next 10 months Colin wants to save $900 for his vacation. He plans to save $75 each for 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?

If you would like to know how much money must Colin save each of the last two months in order to meet his goal, you can calculate this using the following steps:

8 months * $75 = 8 * 75 = $600

$900 - $600 = $300

$300 / 2 months = $150 each month

Result: Colin must save $15 each month.
