Consider the equation ax^2 + b•x + c =m•x+d where a, b, c, m, and d are all constants.

Given the graph above what values of x. make the statement ax^2+ b•x+ c = m•x+d true?

Hey there!

When answering word problems, be careful of the information you don't need. In this case, it's not important to know that the bus pass was originally worth $30. We only need to know how many rides he took and how much he paid for all of those rides total. 

If he rode 12 times and the total cost was $24, that means that you could divide 24 by 12 to get the amount per ride:

$24 ÷ 12 = $2

Each ride cost $2 each. $2 will be your answer. 

Hope this helped you out! :-)
