Exploring Proportions in Discounts, Taxes, and Tips

What type of math problems are discussed in the video?

• Discount, tax, and tip problems

• Algebra problems

• Probability problems

• Geometry problems

If a jacket originally costs $85 and is now 25% off, what is the adjusted percent you are paying?

• 25%

• 75%

• 50%

• 100%

What is the first step in solving a discount problem using proportions?

• Setting up an equation

• Finding the adjusted percent

• Cross-multiplying

• Setting up a proportion

How do you find the adjusted percent when something is 25% off?

• Divide 25% by 100%

• Add 25% to 100%

• Subtract 25% from 100%

• Multiply 25% by 100%

What is the final cost of a jacket that is $85 with a 25% discount?

• $63.75

• $70.00

• $85.00

• $92.00

What is the total bill if Joe and Alex leave an 8% tip on a $42 bill?

• $42.00

• $45.36

• $46.00

• $50.00

How do you calculate the tip amount using proportions?

• Cross-multiply the total bill and the tip percent

• Subtract the tip percent from 100%

• Set up an equation with the total bill

• Set up a proportion with 100% and the tip percent

What is the tip amount if the bill is $42 and the tip percent is 8%?

• $4.20

• $4.00

• $3.36

• $3.00

Why do you not adjust the percent when calculating a tip?

• Because the tip is added to the total

• Because the tip is subtracted from the total

• Because the tip is already included in the total

• Because the tip is a fixed amount

What is the best way to start solving these types of problems?

• Start with 100% in the proportion

• Start with the original price

• Start with the total amount

• Start with the adjusted percent
