At the movie theatre, child admission is $5.20 and adult admission is $9.00 . On Saturday, 156 tickets were sold for a total sal

We can solve this by using systems of equations.

Let's find our first formula, how much money was made using the tickets.

$5.20x + 9y = 1027.80$

Here x is how many child tickets we sold and y is how many adult tickets we sold. Now that we have defined that, we can make another formula for the total tickets sold!

$x + y = 156$ since we sold 156 tickets that could be any combination of child and adult tickets.

Let's solve this system. I'm going to use <em>substitution</em> so I'm going to take our second formula and subtract both sides by x to get $y = 156 - x$ .

Now I will plug this in the first equation for y to get You plug it in for y to get $5.20x + 9 (156-x) = 1027.8.$

From this you can solve for x to get $x = 99$ .

Since $x + y = 156$

$99 + y = 156$

$y = 57$

There were 99 child tickets and 57 adult tickets.

What does algebra mean in math

Algebra is solving for the unknown so
if you have 10 apples and you give 5 to your friend, how many apples would you have so that is also 10-5=x solve for x

or it could be more complicated like (x-2)/6+4x-3=17
