So the Emergent Math family moved houses this weekend (editor’s note: they didn’t actually move the houses, they moved the furniture inside the houses). We were given basically three different options for U-Haul rentals of increasing size and increasing price. This led me to believe that a **nice systems problem** could be constructed from this.

I still feel that way, but it sort of got away from me. I think the idea of deciding which**truck to rent + various mileage costs** is pretty decent. But then things sort of spiraled out of my control and I ended up with a convoluted problem that was actually kind of tedious.

So I’m asking my faithful readership to help me out. I’ve split the problem up into two pieces – as I probably would have in a classroom setting. **Help me make this problem better!**

Basic gist of the problem:

Moving houses (ed. note: again, just the furniture – the author was not living in a double-wide). Three different U-Haul options of increasing square footage (733, 865, and 1015 cubic feet) with three different up-front costs for the U-Haul ($19.95, $29.95, and $39.95, respectively). Also, mileage costs $0.79 per mile – hence the**nice linear functionality** of the problem. **Determine which U-Haul I should rent.**

Best improvement to the problem gets a **free oven mitt**!

This problem has a lot of messiness, which is good for PBL. However it is more a min/max problem, because you don’t really know how many trips each of these trucks will need. I.e., the biggest truck could be anywhere from 2 to 5 trips. Perhaps plotting the points would result in a general area of costs on a grid.
