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(1050y) = 7350
8y + 5250  5y = 7350
3y = 7350  5250
y = 2100/3 = 700
Substt. the above in eqn2
x = 1050  700 = 350
Therefore, 350 children and 700 adults attended the fair.
