The cost of a ticket to the circus is $14.00 for children and $32.00 for adults. On a certain day, attendance at the circus was
Evgesh-ka [11]

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

14(x+y=1000)\\14x+14y=14000\ \ \ Eqn\ 3

Subtracting Eqn 3 from Eqn 2

(14x+32y)-(14x+14y)=24800-14000\\14x+32y-14x-14y=10800\\18y=10800\\

Dividing both sides by 18

\frac{18y}{18}=\frac{10800}{18}\\y=600

Putting y=800 in Eqn 1

x+600=1000\\x=1000-600\\x=400

400 children and 600 adults bought tickets.
