Understanding Percent Change in Prices

Mr. Maisonette's tutorial covers solving word problems involving percent change. It includes two examples: a jacket price increase and a television price decrease. The tutorial explains how to calculate percent change using a formula, convert decimal values to percentages, and interpret results as increases or decreases. Simplification techniques and tips for handling non-cancelable fractions are also discussed.

What is the main focus of this tutorial?

• Solving algebraic equations

• Understanding percent change in word problems

• Learning about fractions

• Studying geometry

In the first example, what was the original price of the jacket?

• $150

• $180

• $189

• $200

What is the first step in calculating the percent change?

• Divide the new price by the original price

• Add the original and new prices

• Subtract the original price from the new price

• Multiply by 100

How do you convert a decimal to a percentage?

• Subtract 100

• Divide by 100

• Multiply by 100

• Add 100

What was the percent change in the jacket's price?

• 20%

• 5%

• 10%

• 15%

In the second example, what was the original price of the television?

• $350

• $391

• $460

• $500

What indicates a price decrease in the calculation?

• A negative result

• A positive result

• A result of zero

• A result greater than 100

What was the percent change in the television's price?

• 15% decrease

• 20% decrease

• 10% increase

• 5% increase

What should you do if simplification is not possible?

• Express the value as a decimal

• Ignore the problem

• Multiply by 1000

• Add the original and new prices
