Q. Problem 24:(first taught in lesson 79)Alan bought a fencing foil for $56. When he went to the cash register, the total including the sales tax was $60.20. What was the sales tax rate? (You can use a calculator.)
Find Sales Tax Amount: First, we need to find the amount of sales tax Alan paid.Total cost including tax: $60.20Cost of the fencing foil before tax: $56.00Sales tax amount = Total cost including tax - Cost before tax
Calculate Sales Tax: Now we perform the subtraction to find the sales tax amount.Sales tax amount = $60.20 - $56.00Sales tax amount = $4.20
Determine Sales Tax Rate: Next, we calculate the sales tax rate. The sales tax rate is the sales tax amount divided by the cost before tax, then multiplied by 100 to get a percentage.Sales tax rate = (Sales tax amount/Cost before tax)×100
Calculate Sales Tax Rate: Now we perform the division and multiplication to find the sales tax rate.Sales tax rate = ($4.20/$56.00)×100Sales tax rate = 0.075×100Sales tax rate = 7.5%
