The taxable amount was $80.86
Step-by-step explanation:
Given,
Sales tax = .07
Total grossed = $1236.00
Let,
x be the price before sales tax, therefore,
Amount of sales tax = 0.07x
Price before sales tax + Sales tax = Total amount grossed
x+0.07x = 1236
1.07x=1236
Dividing both sides by 1.07
Taxable amount = Total amount grossed - Price before tax
Taxable amount = 1236 - 1155.14 = $80.86
The taxable amount was $80.86
