A store manager decides to clear out school supplies to make room for new
inventory. Now a $20 bookbag will be
on sale for only $9. What is the
discount, as a percentage?
A:55%
B:40%
C:45%
D:50%

it would be A:55%

Step-by-step explanation

For percent, to make it easier try to turn it into a 100.

20x5=100

do the same to the 9.

9x5=45.

Now subtract 45 from 100.

100-45=55.

There was a discount of 55%.

Option C. 45%

Step-by-step explanation:

If you divide 9 by 20 you get 45% the to proof it just multiple 45% by 20 and you should get 9 as your answer for that's why I think its 45%
