A man realizes he lost the detailed receipt from the store and only has the credit card receipt with the after-tax total. If the after-tax total was $1,413.10, and the tax rate in the area is 8.7%, what was the pre-tax subtotal?

Respuesta :

Answer:

The pre-tax amount was $1300.

Step-by-step explanation:

Given that:

After-tax total = $1413.10

Tax rate in the area = 8.7%

The pre-tax price would be 100% and this tax rate is an addition.

Total percent = (100+8.7)% = 108.7%

Let,

x be the pre-tax amount.

108.7% of x = 1413.10

[tex]\frac{108.7}{100}x=1413.10\\1.087x = 1413.10[/tex]

Dividing both sides by 1.087

[tex]\frac{1.087x}{1.087}=\frac{1413.10}{1.087}\\x= 1300[/tex]

Hence,

The pre-tax amount was $1300.
