yes, no idea, or
yes, here's my idea?
If no idea, look at the last two problems. There must be some first step you could make.

hint: each share is 1/3 the total cost.
hannah
7.15 =1/3 P+4.50
or 7.16=1/3 (p+4.50)
or 7.16=1/3 (p+4.50)
Steve
total cost is (p+4.50)
so, the 2nd equation is correct (except for the typo :-))
