Let the price be p. Then 1.10p = $8.25. Solving for p, p = $750 (answer)
The equation can be framed as follows:
Before tax cost *(1+tax rate) = Final cost
Given tax rate = 10% = 0.1
Final cost = $825
Before tax cost *(1+0.1) = 825
Before tax cost * 1.1 = 825
Before tax cost = 825/1.1
Before tax cost = $750
Price of the couch before taxes = $750
