Calculating Discounts and Final Prices

The video tutorial explains how to calculate the final price of a cell phone after two successive discounts. Initially, the phone is marked down by 15%, reducing the price to 85% of the original. Then, an additional 10% discount is applied to the new price, resulting in a final price of 76.5% of the original cost. The tutorial walks through each step of the calculation, ensuring a clear understanding of how to apply successive percentage discounts.

What is the price of the cell phone after a 15% discount?

• 0.85X

• 0.15X

• 0.75X

After the first discount, the phone is marked down by an additional 10%. What percentage of the reduced price does it now cost?

• 90%

• 10%

• 85%

• 95%

What is the final price of the cell phone after both discounts?

• 0.85X

• 0.95X

• 0.765X

• 0.9X

How do you calculate the final price after two successive discounts of 15% and 10%?

• Subtract 25% from the original price

• Multiply the original price by 0.85 and then by 0.9

• Multiply the original price by 0.9 and then by 0.85

• Add 15% and 10% to the original price
