Multiple Choice

What is the service fee for a ticket that costs $65 using the percent equation?

• $2.60

• $2.75

• $2.80

• $2.90

Exploring Percentages:

To convert a percent to a decimal, divide it by 100. In this case, 65% becomes 0.65. Therefore, p = 0.04 * 0.65 = 0.026. Simplifying further, p = 2.6%. The service fee is $2.60.
