Answer:
600
Step-by-step
Think of 0.2 as just 2, if you were to divide 120 by 2 it is simple to solve, the answer is 60, now go back to 120 ÷ 0.2. The best way to think about this is to take the 0 from 0.2 and add it to your answer of 60 sense 0.2 is in the tenths place.

13.47=s
13.5~ s
The sales tax was $3.49.
First, you just subtract 69.78 from 100, and you get 30.22. Then you subtract 26.73 from 30.22 and you get 3.49.

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.
