Answer:
He earns $184 in commission yesterday.
Explanation:
A watch salesman earns a commission 40% of all watch sales made.
He sold yesterday 5 watches = $60.00 each
Price of 5 watches = 60.00 × 5 = $300
4 watches = $40.00 each
Price of 4 watches = 40.00 × 4 = $160
Total sales made = 300 + 160 = $460
His commission is 40% of the sales = 40% × 460
= 0.40 × 460 = $184
He earns $184 in commission yesterday.
