I don’t understand you second question but this is the work for the first one.
Hope it helps!
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
So, for a score of 90, the number of study hours needs to be ...
90 = 30 +2.5h
60 = 2.5h
60/2.5 = h = 24
Jesse needs to study 24 hours to get a score of 90.
