Each input should only have 1 output. Multiple inputs can have the same output, but one input can only correspond to a single output.

Answer:
24 hours
Step-by-step explanation:
It appears that the score (s) is related to the number of hours (h) by ...
s = 30 +(10/4)h

60 = 2.5h
60/2.5 = h = 24
Jesse needs to study 24 hours to get a score of 90.
