Final answer:
To calculate the total price of a tennis racket with a 7% sales tax, convert 7% to a decimal (0.07) and multiply by the racket's price to find the tax amount ($12.60). Add this to the original price to get the total cost, which is $192.60.
Step-by-step explanation:
The question pertains to the calculation of the total price of a tennis racket after including sales tax. The racket costs $180 and the sales tax is 7%. To find the total cost, one must first convert the percentage to a decimal by dividing by 100. Thus, 7% becomes 0.07. The next step is to multiply the price of the racket by this decimal to find the sales tax amount.
$180 × 0.07 = $12.60
This is the amount of sales tax. To find the final price, add the sales tax to the original price of the racket:
$180 + $12.60 = $192.60
Therefore, the total price of the tennis racket, including the 7% sales tax, is $192.60.
