Question

Donte and Trista both bought the same three-ring binder for $5. Donte lives in Arizona and pays 5.6% in sales tax, while Trista lives in New Jersey and pays 7% in sales tax. How much more did Trista pay in sales tax than Donte?

Answer 1

Sales tax paid by Donte =
`(5.6)/(100) (5)`

= 0.28

Sales tax paid by Trista =
`(7)/(100) (5)`

= 0.35

The extra tax paid by Trista = 0.35 - 0.28 = 0.07.

Hence, Trista paid $0.07 more than Donte.
