A surfboard has a price of $920. With sales tax, it will cost $1,012. What is the sales tax percentage?

Answer: 10%

Step-by-step explanation:

Let the sale tax = $x

Cost price (CP) of the surfboard = $920

Sale tax with cost price of the surfboard = $1,012

Therefore the sale tax ($x) = $1,012 - $920

=$92

Therefore the sale tax percentage = ⁹²/₉₂₀ x 100

= 10%
