Derek’s favorite clothing store is having their annual fall sale. All clothing is 25 percent off. A shirt he really likes has an original price of $28. Derek has $24 in his wallet. He is wondering if he has enough money to buy the shirt now that it is on sale. He knows he must also pay sales tax. The sales tax rate is 8 percent and is calculated on the discounted price. Does Derek have enough money to buy the shirt?

so 28 dollars-25%
25%=25/100=0.25

so 25 percent off means the price is 100-25=75%

so the priceof sale=0.75 times 28=21

then 8% tax which is 0.08
21+(21 times 0.08)=21+1.68=22.68

the total price/end price with tax=22.68

22.68<24 so he has enough money
