Tomas bought a book that originally cost $25.99 on sale for 25% off. He paid 6% sales tax. To the nearest cent, how much did Tom
Andru [333]

25.99 \times  \frac{25}{100}  = 6.4975 \: or \: 6.5

thus meaning that $6.5 will be removed.

25.99 - 6.5 = 19.49

the price before tax is now $19.49 or 19.5

now for the tax

19.49 \times 6\% = 1.1694 \: or \: 1.2

now we add

19.49 + 1.2 = 20.69

your total is $20.7
