9.

The grad committee has raised \$1420 over the school year in fundraising activities. They are planning on using the money to pay for the grad dinner and dance. The DJ costs \$250 for the evening. The cost of the dinner is \$15/person.
Write an equation to represent the problem, where n represents the number of people who attend.
 a. n + 250 = 1420 c. 15n + 250 = 1420 b. 15n = 1420 d. 10.

Solve the equation from question 9 to determine the number of people the grad committee can allow to attend the dinner and dance.
 a. 80 b. 79 c. 78 d. 77
