Answer 1

To find the sales tax, multiply the cost of the item by the tax rate. Add the sales tax to the cost to find the total cost.

Step-by-step explanation:

To find the sales tax, multiply the cost of the wireless mouse by the tax rate. In this case, the tax rate is 5.1%, which can be written as 0.051 in decimal form. Thus, the sales tax is $15.99 x 0.051 = $0.81549. Rounding to the nearest cent, the sales tax is $0.82.

To find the total cost, add the cost of the wireless mouse to the sales tax. The total cost is $15.99 + $0.82 = $16.81. Rounding to the nearest cent, the total cost is $16.81.
