Answer:
8 cups of hot chocolate
Step-by-step explanation:
400 children and 600 adults bought tickets.
Step-by-step explanation:
Given,
Cost of one child ticket = $14
Cost of one adult ticket = $32
Total attendance = 1000
Revenue generated = $24800
Let,
x be the number of children.
y be the number of adults.
According to given statement;
x+y=1000 Eqn 1
14x+32y=24800 Eqn 2
Multiplying Eqn 1 by 14

Subtracting Eqn 3 from Eqn 2

Dividing both sides by 18

Putting y=800 in Eqn 1

400 children and 600 adults bought tickets.
