Answer:
Warning Signs Your Tires Need to Be Rotated
Uneven wear between tires. Tire one side wear. ...
Vehicle vibration. At speeds of 45 mph and higher, you may feel a vibration, which may be caused by uneven wear. ...
Pressure loss. If one tire loses air slowly, yet faster than the others, it may mean too much pressure is put on it.
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>
