MULTIPLE CHOICE QUESTION

30 sec • 1 pt

Disney held a breakfast for parents and their children to eat with Mickey Mouse. ADULT tickets cost $17.95 and CHILD tickets cost $12.95. Disney sold a total of 500 tickets and collected $7355 from sales.

Choose the system that represents this situation.

Let "a" represent the # of ADULT tickets and "c" represent # of CHILD tickets.

17.95a + 12.95c = 500

17.95a + 12.95c = 7355

a + c = 500

17.95a + 12.95c = 7355

a + c = 7355

17.95a + 12.95c = 500
