Abookstore employee is given a 20% discount off the retail price of any book. assuming there is no tax, how many dollars does she pay for a book with a retail price of $55?

 = $ 49.5

Step-by-step explanation:

We are given;

Required to determine the amount paid

Taking the retail price as 100%

Then, amount paid will be (100 % - 10%) 90% of the retail price

Therefore;

Amount paid = 90% × $ 55

                     = 0.9 × $ 55

                     = $ 49.5

Thus, the employee paid $ 49.5 for the book.

you just switch the numbers basically so it would be 3/17
