Question

A model spaceship costs $15.99before tax the tax on the model spaceship is 8% what is the total cost of the model spaceship round your Anwer to the nearest cent

Answer 1

There are two ways to find the total with tax

Either you can do

cost + cost x tax rate

or

cost x (1+tax rate)

Since the second one requires less steps, it's easier to do that.

$C = 15.99\times(1+.08)\\C= 15.99\times(1.08)\\C =17.2692\\C\approx17.27$

The cost with tax is

$17.27
