Question

sue find a cd she likes that normally costs $19.99. if the cd is labeled 75% off, and the sale tax rate is 5.5% (of the sale price), what will be the total cost of the cd?

Answer 1

if it is 75% off, then she paid 25% of it

0.25(19.99) = 4.99 rounds to 5.00

plus the sales tax of 5.5%...
5.00 + 0.055(5) = 5 + 0.28 = 5.28 <==
