The answer to your question is: 54°F
Step-by-step explanation:
Data
Ti = 78°F
Initial hour = 2:00
Temperature drops 4°F every hour
Temperature at 8:00 = ?
Process
2:00
3:00 78-4 = 74°F
4:00 74-4 = 70°F
5:00 70-4 = 66°F
6:00 66-4 = 62°F
7:00 62-4 = 58°F
8:00 58-4 = 54°F
To answer this question, it is easier to make a list of the repair cost based on the hour of labor. The first hour is $45 then after that $25/hour. Then the list would look like
0-1 h= $45
1-2h= $70 ($45 +1*$25)
2-3h= $95 ($45 +2*$25)
3-4h= $120 ($45 +3*$25)
Looking at the list, the answer should be
<span>B. C(t) = 95 for 2 < x ≤ 3</span>
