To create an equation from a table use LISTS & SPREADSHEET, DATA & STATISTICS, MENU 4, 6, 1.

To create an equation from a graph choose two points and use LISTS & SPREADSHEET, DATA & STATISTICS, MENU 4, 6, 1. Or, you can also create the equation by using SLOPE-INTERCEPT FORM y = mx + b. Find the slope from RISE/RUN and the Y-INTERCEPT by checking where it crosses the y-axis.

Since they are asking you to create a system of equations, it helps to separate the problem into two equations that focus on WHAT they are talking about and THE COST of what they are talking about. Make sure the numbers make sense with the variables and the total. Call me for help if you don't understand.
