Calculating Purchase Price with Discounts and Sales Tax

This video tutorial from Moomoomath explains how to calculate the final purchase price of an item when a discount and sales tax are applied. The process involves two main steps: first, calculating the discounted price by subtracting the discount from the original price, and second, adding the sales tax to the discounted price to find the final purchase price. The video provides two examples: one for a shirt and another for shoes, demonstrating the calculations in detail. The tutorial concludes with a prompt to subscribe for more math videos.

What is the first step in calculating the purchase price when a discount is involved?

• Divide the original price by the discount percentage.

• Multiply the original price by the sales tax.

• Subtract the discount from the original price.

• Add the sales tax to the original price.

How do you convert a percentage to a decimal for calculation purposes?

• Multiply by 100.

• Add 100 to the percentage.

• Subtract 100 from the percentage.

• Divide by 100.

In the shirt example, what is the discounted price before adding sales tax?

• $27.71

• $37.00

• $11.10

• $25.90

What is the final purchase price of the shirt after applying the discount and sales tax?

• $11.10

• $37.00

• $27.71

• $25.90

In the shoes example, what is the amount of discount applied?

• $7.35

• $9.00

• $15.00

• $49.00

What is the discounted price of the shoes before adding sales tax?

• $45.39

• $41.65

• $7.35

• $49.00

What is the final purchase price of the shoes after applying the discount and sales tax?

• $41.65

• $49.00

• $45.39

• $7.35

What is the second step in calculating the purchase price after finding the discounted price?

• Divide the discounted price by the sales tax rate.

• Add the original price to the discounted price.

• Multiply the discounted price by 1 plus the sales tax rate.

• Subtract the sales tax from the discounted price.

How is the sales tax rate converted to a decimal?

• Add 100 to the rate.

• Multiply by 100.

• Subtract 100 from the rate.

• Divide by 100.
