Answer 1

120 coupons were used; yes, she should run the sale again

Step-by-step explanation:

The total number of customers = 600

The percentage that used coupon = 20%

`\begin{gathered} 20\%\text{ of 600} \\ =(20)/(100)*600 \\ =120 \end{gathered}`

Thus, 120 coupons were used.

Since more than 100 coupons were used, the manager should run the sale again.
