Solving (a): (g + f)(2)
This is calculated as:
Calculate g(2) and f(2)
So:
Solving (b):
This is calculated as:
Calculate f(-1) and g(-1)
So:
Solving (c): (g - f)(-1)
This is calculated as:
Calculate g(-1) and f(-1)
So:
Solving (d): (g * f)(2)
This is calculated as:
Calculate g(2) and f(2)
So:
Answer:

Answer:
89 rooms should be set for early book customer
Step-by-step explanation:
According to the given data we have the following:
OVERAGE(CO) = 200
SHORTAGE(CS) = 500
In order to calculate how many rooms should be set for early book customer we would have to use the following formula:
OPTIMAL BOOKING = MEAN + (Z * STDEV)
MEAN = 75
STDEV = 25
SERVICE LEVEL= CS / (CS + CO) = 500 / (500 + 200) = 0.7143
Z VALUE FOR 0.7143 = 0.57
OPTIMAL BOOKING = 75 + (0.57 * 25) = 89
89 rooms should be set for early book customer
