I honestly don’t understand can some please help?

Answer:
400$
Step-by-step explanation:
since he receives 20 percent of the sales and he receives 80 dollars. Then 80 dollars is 20 percent of the sales. Now, we can change 20 percent into a fraction, 20 percent is 20/100 or 2/10, now there are 5 twos in a ten so we multiply 2/10 by 5, since 2/10 right now is 80 dollars you multiply 80 by 5
80*5=400, so the sales of the week was 400 dollars
Hope this helps :)
Answer:
Thus, the sales of the week were $400
Step-by-step explanation:
Percentages
The salesman receives a 20% commission on all his sales.
One week the company pays $80 as commission.
This means that $80 corresponds to 20% of the sales.
To find the sales, we just divide the commission by the percentage (expressed as a decimal) as follows:
Sales = $80 / (20/100)
Sales = $80 / 0.20
Sales = $400
Thus, the sales of the week were $400
