<span><u><em>Answer:</em></u> Kevin made $800 in commissions last week.
<u><em>Explanation:</em></u> Since we know that he only makes money in two ways, by base salary and commission, we know that added together they equal his whole pay.
<u>Therefore we can set up the following equation and solve for his commission amount. </u> Total Pay = Base Pay + Commissions. 1125 = 325 + Commissions. 800 = Comissions. </span>
