Roses-R-Red sells its roses for a fixed down payment of $20 plus $0.75 per stem.  Flower Power sells its roses for a fixed down payment of $60 plus $0.50 per stem.  Which company offers the better deal? Which flower distributor would you use? why?

Steve · Answer

depends on how many you want to buy. RRR<FP if

20+.75n < 60+.50n

So, RRR is cheaper if you buy fewer than 160 roses.

But, it's well known that the creeps at Flower Power are just a gang of thugs, so I'd never use them no matter how much it cost!
