A community sponsored a charity square dance where admission was $3 for adults and $1.50 for children. if 168 people attended the dance and the money raised was $432, how many adults and how many children attended the dance?

a. what

Okay, we need two equations for this:

a will represent adults, and k, kids

a + k = 168

a = 168 - k

300a + 150k = 43200

Replace a:

300 (168-k) + 150k = 43200

50400 - 300k + 150k = 43200

-150k = - 7200

15k = 720

k = 48

168 - 48 = 120

46 children and 120 adults attended
