Answer:
x = $240
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⋅0.085
Next, substitute the value into the equation:
Original Cost + Sales Tax Amount = Total Cost
x+0.085x=260.40
Add like terms.
1.085x=260.40
Divide both sides by 1.085 to isolate the unknown value.
x=$240
The original cost of the bike rack was $240.
