Question 1182969
p=ks where k is the constant of proportionality. P is directly proportional to s. This problem.
p=k/s, P is inversely proportional to s, so if s rises P falls.

What models this relationship is p=2s
numbers 2 and 4 don't work, and while p is equal to s+3, that is not proportional, for 2s should equal 12 in the problem above, but 2s+3 would be 9.
