Question

If 147 people attend a concert and tickets for adults cost 2.50 while tickets for children cost 1.50 and total receipts for the concert was297.50 how many of each went to the concert

Answer 1

Explanation:

a + c = 147

2.50a + 1.50c = 297.50

-2.50a - 2.50c = -367.50

2.50a + 1.50c = 297.50

-c = -70

c = 70 children

a + 70 = 147

a = 77 adults
