Question

You paid 8.25% sales tax when you purchased a $649 phone Including the sales tax, how much did you pay ?

Answer 1

The cost of the article is $649, since we are paying not only the cost of the phone but taxes we have to add the amount payed in taxes to the $649, we can calculate the taxes by multiplying the sales tax rate, 0.0825 (8.25%), and the $649, then we get:

taxes = 0.0825×649 = 53.5425

By adding $53.5425 to the initial $649, we get how much did we pay in total, then we get:

Total cost = $702.5425
