Question

A bicycle has a listed price of $619.98 before tax. If the sales tax rate is 7.5% , find the total cost of the bicycle with sales tax included.

Answer 1

1. find 7.5% of 619.98
0.075 x 619.98 = 46.4985
so about 46.50
that's how you find the sales tax

2. add the sales tax to the listed price to find the total cost with sales tax included
46.50 + 619.98 = 666.48

Answer 2

Hey there.

We can calculate the total cost by multiplying the price before tax by the decimal form of the sales tax.
This translates to:

619.98 · 0.075 = 46.50 (rounded)

Now we add the listed price and the tax.

619.98 + 46.50 = 666.48

The total cost the bicycle is $666.48
