I don't see any choices, but I imagine your teacher wants the function written in y=mx+b form.  "b" represents the y-intercept, or the starting point (the flat fee.)  "m" represents the slope, or the rate of change, which is 1.25 per night.  "x" would be the number of nights, and "y" is the total cost.  The cost, or "y" depends on "x," the number of nights. Just plug in the values for m and b and you should have the function you're looking for.

the function u would end up with is f(x) = 1.5 + 1.25x
because u multiply $1.25 for each night with x and add 1.50 for a flat fee

the dog is correct, though I was hoping we would give Delgado a chance to figure it out.
