Question

At the movie theatre, child admission is $6.00 and adult admission is $9.20 . On Wednesday, four times as many adult tickets as child tickets were sold, for a total sales of $1455.20 . How many child tickets were sold that day?

Answer 1

Let the number of child tickets be x. Then the number of adult tickets is 4x. We can write the following equation:
6x + (9.2 * 4x) = 1455.2
which can be simplified to:
6x + 36.8x = 1455.2 ............(1)
Now you just need to solve equation (1) to find the value of x. Can you do that?

Answer 2

The first step in solving equation (1) is to add the two terms on the left hand side. Can you do that and post your result?

Answer 3

@kropot72 I'm working on it

Answer 4

i got 236.4

Answer 5

6x + 36.8x = ? x
Just add the two coefficients of x.

Answer 6

So what is 6 + 36.8 ?

Answer 7

@kropot72 42.8

Answer 8

Correct! So equation (1) simplifies to:
42.8x = 1455.2 ............(2)
Now if you divide both sides of equation (2) by 42.8 you will have the value of x:
\[x=\frac{1455.2}{42.8}=you\ can\ calculate\]

Answer 9
