Children and adults purchased tickets for a local amusement park. all tickets were sold at the park entrance-season passes, discount, atc. we’re not allowed. A child’s tickets cost $8 while an adult ticket cost $15.A total of 5,500 was collected.600 tickets were sold. how many of each type of ticket were sold?

x = number of children tickets sold = 500

y = number of adult tickets sold = 100

Step-by-step explanation:

Let

x = number of children tickets sold

y = number of adult tickets sold

x + y = 600 (1)

8x + 15y = 5,500 (2)

From (2)

x = 600 - y

Substitute x = 600 - y into (2)

8x + 15y = 5,500 (2)

8(600 - y) + 15y = 5,500

4,800 - 8y + 15y = 5,500

- 8y + 15y = 5,500 - 4,800

7y = 700

y = 700/7

y = 100

Substitute y = 100 into (1)

x + y = 600 (1)

x + 100 = 600

x = 600 - 100

x = 500

x = number of children tickets sold = 500

y = number of adult tickets sold = 100

for the first question it would be the second answer for the second question it would be the third answer and for the third question it would be the first answer
