Question

Marsha is buying snacks for her party and she spends $29.12 and the sales tax is 6%. What is her total?

Answer 1

After paying for the value of the goods and taxes, we will pay 100%+6%=106% of $29.12; this is, the price of the snacks (100%) plus taxes (6%).

Remember that 100%=1, and 6%=0.06; therefore 106%=1.06.

Then,

`29.12\cdot(1.06)=30.8672\approx30.87`

If taxes have to be applied to the $29.12 cost, the total will be $30.8672, approximately $30.87.

On the other hand, if taxes have already been applied to the $29.12 cost, the original price of the product without taxes is

`29.12\cdot(1-0.06)=29.12(0.94)=27.3728\approx27.37`
