Eitan sells a mean of $8000 worth of merchandise with a standard deviation of $1500 each month.
melisa1 [442]

Answer:

t = $4400 +/- $450

mean = $4400

standard deviation = $450

Step-by-step explanation:

Given;

Base salary b = $2000

Sales s = $8000 +/- $1500

Commission c = 30% sales = 0.3 × s

Total Salary t = base salary + commission = b + c

Commission c = 0.3×s = 0.3×($8000 +/-$1500)

c = $2400 +/- $450

Total salary t = b + c

Substituting the values;

t = $2000 + ($2400 +/- $450)

t = $4400 +/- $450

mean = $4400

standard deviation = $450
