Remember that u will always know what ten percent is

Divide it by 5 and that is your discount

20 percent off is one fifth, so one fifth of 90 is 90 divided by 5 is 18, 90-18=72. your shoes will cost \$72 + tax.

U can always do a quick math by multiplying. Any % x the amount to get ur answer..2 (20%) x 9 (90.00) = 18.00..... = 72.00
