Answer: 279.
Step-by-step explanation:
First, change the percentage to a decimal and write the equivalence of the sales tax amount. Let x be the original cost of the item.
Sales tax amount =x⋅0.08
Next, substitute the value into the equation:
Original Cost + Sales Tax Amount = Total Cost
x+0.08x=301.32
Add like terms.
1.08x=301.32
Divide both sides by 1.08 to isolate the unknown value.
x=$279
