If 126 people attend a concert and tickets for adults cost $4.00 while tickets for children cost $2.25 and total receipts for the concert was $383.25, how many of each went to the concert?

Respuesta :

Answer:

69 children, 57 adults

Step-by-step explanation:

Let a = number of adults and c = number of children.

a + c = 126---------------->4a + 4c = 504

4a + 2.25c = 383.25-->4a + 2.25c = 383.25

----------------------------

1.75c = 120.25

c = 69, a = 57
