Question

A book store is offering 10% off your total bill. If you owe $130.50 how much was your bill before the incentive

A)$117.45

B)$145

C)$162.34

D)$150

Answer 1

The answer is B. 145

To find the answer you divide 130.50 by the remaining of the 100%

So divide 130.5 by .9 if that makes sense.

Hope this helps.

Answer 2

Your bill before the incentive was $145

Explanation:

Let the original price be x

A book store is offering 10% off your total bill.

So, Cost after applying offer =
`x-10\%x`

=
`x-(10)/(100)x`

=
`(90)/(100)x`

We are given that you owe $130.50

So,
`(90)/(100)x=130.50`

`x=130.50 * (100)/(90)`

`x=145`

So, Option B is true

Hence your bill before the incentive was $145
