Answer:
John Hughes won in the month a total of $4405
Step-by-step explanation:
if we have that Jhon earns a salary of $ 2800 and a commission of 7.5% of the sales he made for a value of $ 21400
to know the gain of jhon we have to add the basic salary with the percentage of what he sold
x = 2800 + 21400 * 7.5%
7.5% can be expressed as 7.5/100
x = 2800 + 21400 * 7.5/100
x = 2800 + 21400 * 0.075
x = 2800 + 1605
x = 4405
