If 104 people attend a concert and tickets for adults cost $3.75 while tickets for children cost $2.5 and total receipts for the concert was $313.75, how many of each went to the concert?

Answer 1

If A = adults and C = children the problem tells you that

A + C = 104 and

3.75A + 2.5C = 313.75

When you solve this simultaneous equation, you find that

A = 43

C = 61
