child's fair ticket is $5 and adult fair ticket are $5. 1050 people attend the fair. fair collects $7350. how many of each type of ticket were sold?

sorry.

child is $5 and adult is $8

Try this:

x = no. of children attending the fair
y = no. of adults attending the fair

so, 5x + 8y = 7350 (eqn 1)

x + y = 1050 (eqn 2)
x = 1050 - y

Substt. the above in eqn 1,

8y + 5(1050-y) = 7350
8y + 5250 - 5y = 7350
3y = 7350 - 5250
y = 2100/3 = 700

Substt. the above in eqn-2

x = 1050 - 700 = 350

Therefore, 350 children and 700 adults attended the fair.
