Percent Change

The video tutorial explains how to calculate the percent change in value, using a baseball card as an example. Initially purchased for $4, the card's value increased to $7 after a grand slam. The percent change is calculated by comparing the difference between the original and new values to the original value, using a specific formula. The tutorial walks through the calculation process, resulting in a 75% increase. The lesson concludes with a summary of the key concepts learned.

What was the original value of the baseball card before the player's grand slam?

• $3

• $7

• $4

• $5

Which of the following best describes the percent of change?

• The sum of the original and new values

• The comparison of the difference between the original and new value to the original value

• The ratio of the new value to the original value

• The difference between the new and original value

What is the first step in calculating the percent of change?

• Divide the new value by the original value

• Find the absolute value of the difference between the original and new value

• Subtract the new value from the original value

• Multiply the original value by 100

After calculating the absolute difference and dividing by the original value, what is the next step?

• Divide the result by 100

• Add 100 to the result

• Multiply the result by 100

• Subtract 100 from the result

What was the percent increase in the value of the baseball card?

• 50%

• 75%

• 60%

• 100%
