A shoe salesman earns a commission of 20% of all shoe sales made. Yesterday he sold 2 pairs of shoes for 80$ each and 3 pairs of shoes for $70 each. How much did he earn in commission yesterday?
The salesman sold 2 pairs of shoes for $80 each, which has the value = of $80×2 = $160.
The 3 pairs of shoes that he sold for $70 each have a value = of $210
The total amount of shoes he got is $160+$210 = $370.
Since he gains 20% commission of the total amount, the commission is:
20%×$370 = $74
Hence, the salesman gained $74 commission yesterday.
