Over the seven-year span of babysitting for the Millard's, Carrie's babysitting rate went from $8 per hour to $14 per hour. What is the percent increase? Round to the nearest percent.

Answers

Answer: 75%

Step-by-step explanation:

Over the course of seven years, Carrie went from charging the Millards $8 to charging them $14 per hour.

To calculate the percentage increase, use the following formula:

= (New price - Old Price) / Old price * 100%

= (14 - 8) / 8 * 100%

= 6/8 * 100%

= 75%

Carrie's rate went up by 75%.
