Problema Solution
Adult tickets to a movie are sold at $10 each, student tickets at $8 each and children't tickets at $5 each. The cinema sold twice as many adult tickets as children's tickets, and the total number of tickets sold to students and children was 80. If the total money collected was $1,150, how many tickets of each type were sold?
Answer provided by our tutors
A = 2C
S + C = 80
S = 80 - C
5C + 10(2C) + 8(80-C)=1150
Solve for C
5C + 20C + 640 - 8C = 1150
17C + 640 = 1150
C = 30 children's tickets
60 Adult tickets
50 student's tickets
