## Elementary Algebra

A guideline for this problem would be New time = Current time - Amount of time reduced The amount of time reduced is found by multiplying the current time by the percent change. So: New time = 220 - 220 $\times$ 8% New time = 220 - 220 $\times$ 0.08 New time = 220 - 17.6 New time = 202.4 His new time would be 202.4 minutes.
