how to solve it?

Question

If 108 people attend a concert and tickets for adults cost $3.5 while tickets for children cost $1.75 and total receipts for the concert was $250.25, how many of each went to the concert?

Answer 1

x = number of adults at 3.50 each

y = number of children at 1.75 each

x + y = 108

3.50x + 1.75y = 250.25

Solve this system by substitution, elimination, or Cramer's rule. I get

x = 35

y = 73
