Answer:
Step-by-step explanation:
let the no of children be x
cost for children = 5.8
total cost for children = 5.8x
let the no of adults be y
cost for adults = 8.9
total cost for adults = 8.9x
total tickets sold = total number of people
125 = x+y
x=125-y
total cost = total cost for children + total cost for adults
954.4 = 5.8x + 8.9y
substitute the value of x
954.4 = 5.8 (125 - y) + 8.9y
954.4 = 725 - 5.8y + 8.9y
954.4 - 725 = 3.1y
229.4 = 3.1y
y = 229.4/ 3.1 = 74
therefore total no of adults = 74
