Lane wants a new video game priced at $55 and sales tax is 7%. What is the total cost of the video game after tax? First, change the percentage to a decimal and find the sales tax amount.

55⋅0.07=$3.85
Now, add the sales tax amount to the original price.

55+3.85=$58.85
The final cost after tax is $58.85.

The sales tax is determined by computing a percent of the purchase price. To find the sales tax multiply the purchase price by the sales tax rate. Remember to convert the sales tax rate from a percent to a decimal number. Once the sales tax is calculated, it is added to the purchase price.
