{30 POINTS} For a promotion, a store offers to pay the sales taxes on any item
you buy. You are actually paying taxes but they are calculated on
a lower price.
Suppose you buy an item for $100.
The sales taxes are 15%.
a) What is the true sale price of the item?
b) How much tax are you really paying?

Respuesta :

--Answer--

1. $85

2. $15

--Explanation--

1. 15% off of 100 just means moving the decimal in 15 over by 2 to the left.

From there, multiply 100 x 0.15.

Then you get 15, so that's how much tax you are paying. Meaning Subtract 15 from 100 to get the price it originally was before tax. 100 - 15 = 85.

2. $15 dollars tax from moving decimal 2 to the left of 15%.
