Question

The Bishop's Peak 4-H club is having its annual fundraising dinner. Adults pay $35 apiece and children pay $25 apiece. If the number of adult tickets sold is twice the number of children's tickets sold, and the total income for the dinner is $2,660, how many of each kind of ticket did the 4-H club sell? adults

Answer 1

35a + 25c = 2660
a = 2c

35(2c) + 25c = 2660
70c + 25c = 2660
95c = 2660
c = 2660/95
c = 28 <=== there were 28 children tickets

a = 2c
a = 2(28)
a = 56 <== there were 56 adult tickets
