Question

Question 7 Unsaved A couch cost $825. If the state has a 10% sale's tax. What was the price of the couch before taxes?

Answer 1

Let the price be p.  Then 1.10p = $8.25.  Solving for p, p = $750 (answer)

Answer 2

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
