5. Pat works in a clothing store where he is paid $650.00 a week, plus 2% commission. In the month of May, he had weekly sales of $9367.50, $7123.75, $12 680.25, and $8764.00. Calculate his earnings for the month.

First, we need to calculate Pat's total commission earned for the month.

Commission for week 1: $9367.50 * 0.02 = $187.35
Commission for week 2: $7123.75 * 0.02 = $142.475
Commission for week 3: $12,680.25 * 0.02 = $253.605
Commission for week 4: $8764.00 * 0.02 = $175.28

Total commission earned for the month: $187.35 + $142.475 + $253.605 + $175.28 = $758.71

Now we can calculate Pat's total earnings for the month.

Total earnings for the month: ($650 * 4) + $758.71 = $2608.71

Therefore, Pat's total earnings for the month of May is $2608.71.
