Hello there. To solve this question, we'll need to pay attention to how much money will be collected for each type of plan the students idealized:
Leanne says that the best is to ask for $1 per mile.
Gilberto says that is better to ask for $2 per mile.
Alana says that asking for $5 and $.5 each mile is the best option.
Making the table:
Now, to graph those plans in the same coordinate plane.
Say x is the amount of miles.
For Leanne, the function will be y = x.
For Gilberto, the function will be y = 2x.
For Alana, the function will be 5 + 0.5x
As we can see in the table, for x = 8, the sponsor would own $8, $16 and $9 respectively on each plan.
