Answer:
expected cost = $2800 per month
Explanation:
given data
Copies (per month) = 4,000
probability = 40%
copies (per month) = 9,000
probability = 60%
lease new copier = $1,050
variable cost = $0.25
to find out
What is the expected cost
solution
we know that expected cost is here
expected cost = fixed cost + variable cost .................1
and here demand of copies per month is express as
= ( 40 % of 4000 ) + ( 60% of 9000 )
= 1600 + 5400 = 7000
so from equation 1
expected cost = fixed cost + variable cost
expected cost = 1050 + 0.25 × 7000
expected cost = 1050 + 1750
expected cost = $2800 per month
