Abicycle 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.

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

~

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
