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:

Your bill before the incentive was $145

Step-by-step explanation:

Let the original price be x

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

So, Cost after applying offer = [tex]x-10\%x[/tex]

                                               = [tex]x-\frac{10}{100}x[/tex]  

                                               = [tex]\frac{90}{100}x[/tex]  

We are given that you owe $130.50

So,  [tex]\frac{90}{100}x=130.50[/tex]  

[tex]x=130.50 \times \frac{100}{90}[/tex]  

[tex]x=145[/tex]  

So, Option B is true

Hence your bill before the incentive was $145
