The rates are described by the following piecewise function:
f(x)= $50 if 0 ≤ x ≤ 60 and 4/3x - 30 if x > 60
Use this function to answer the following questions:
a.) What is the cost if the repair man works for 45 minutes?::
Ans:: $50
-------------------------
b.) What is the cost if the repair man works for 105 minutes?
Ans:: (4/3)(105) - 30 = (420/3) - 30 = $104.33
-------------------------
c.) What is the computer repair man’s rate policy? Explain in real terms
Ans::: ??
