Question

Rose just bought a new jet ski for $5200, and it takes about $45.25 to fill the tank each time she goes out for a ride on the lake.  Write a linear function that models these expenses and interpret the slope in the context of the problem

anonymous · Answer

let R be the number of rides
Total cost = 5200 + 45.25*R
the slope is "how much more money she spends, for every additional ride she goes out on the lake".
