**Steve**, Thursday, September 22, 2011 at 11:44amLet's set up some variables to keep track of the various items of interest.

a = # par-3 holes

b = # par-4 holes

c = # par-5 holes

We are told:

a+b+c=18 holes

b = 7c

a+c = 4

3a+4b+5c = 72 strokes needed to finish course

3(4-c) + 4(7c) + 5c = 72

12-3c + 28c + 5c = 72

30c = 60

c=2

b=14

a=2

And we didn't even need the fact that a+b+c=18, but it works out just fine.
