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.
