Step-by-step explanation:
To find the tax amount on Elmer's tennis racket, you need to multiply the price of the racket by the sales tax rate. In this case, the racket is priced at $69.35 and the sales tax rate is 5.3%.
First, convert the sales tax rate to a decimal by dividing it by 100. 5.3% becomes 0.053.
Next, multiply the price of the racket by the sales tax rate (in decimal form): $69.35 * 0.053 = $3.67255.
Rounding to the nearest penny, the tax amount on Elmer's tennis racket is $3.67.
To find Elmer's total cost, including tax, you need to add the original price of the racket to the tax amount: $69.35 + $3.67 = $73.02.
