____________________________________________________
Step-by-step explanation:
To make solving this equation easier, lets turn the the information we got in the question into an actual equation.
Key information:
4 tickets
$12 popcorn
Spent a TOTAL of $40.
With the information above, we can use it to make an equation.
We would use the equation: y = mx + b
Since our "y" value would represent our total value, our total value is 40, so we would plug 40 into y.
Your equation should look like this:
40 = mx + b
Our "b" value represents our start value, and our start value would be 12 because we started with one $12 popcorn.
Your equation should look like this:
40 = mx + 12
Our "m" value would represent how many tickets we bought, so we would plug in 4 in m.
Our equation would be:
40 = 4x + 12
Now we can solve the equation:
We would move the 12 over to the left side of the equal sign by subtracting, then we would divide by 4.
[tex]40=4x+12\\\\28=4x\\\\7=x[/tex]
We should get ther answer of 7, that means that each ticket cost $7 dollars.
7 dollars should be your FINAL answer.
