Economics Question: price elasticity?

I'm trying to help one of my students with a question for his econ class. The question asks them to compare the relative price elasticities of the following three things: heart transplant surgery, lawn care, and tanning salons. I have a general idea how to answer but wanted to check if anyone here could give a good answer, as econ is not my strength. Thanks in advance!
