Answer:
Ruby should go to college.
Explanation:
Ruby is currently 50 years old and earning $50,000 per year.
She would like to retire at 67.
She is thinking of going back to college, to complete a graduate degree.
After completing a graduate degree from the college she would earn $55,000.
The total cost of a graduate degree is $75,000.
Ruby still has 17 years to work and earn.
Her income will increase by $5,000 after college
The increase in income earned after college until retirement
= $5,000 17
= $85,000
Since the increase in income is greater than the cost of going to college, Ruby should go to college.
Answer:
a) attached below
b) P( profit ) = TR(q) - TC(q)
c) attached below
d) -$5000 ( loss )
Explanation:
Given data:
Fixed Cost = $10,000
Material cost per unit = $0.15
Labor cost per unit = $0.10
Revenue per unit = $0.65
<u>a) Influence diagram to calculate profit </u>
attached below
<u>b) derive a mathematical model for calculating profit.</u>
VC = variable cost per unit , LC = per unit labor cost , MC = per unit marginal cost, TC = Total cost of manufacturing , FC = Fixed cost, q = quantity, TR = Total revenue, R = revenue per unit
VC = LC + MC
TC (q) = FC + ( VC * q )
TR (q) = R * q
P( profit ) = TR(q) - TC(q) ------------ ( 1 )
c) attached below
<u>d) If Cox Electrics makes 12,000 units of the new product </u>
The resulting profit = -$5000
q = 12
P = TR ( q ) - TC ( q )
= ( R * q ) - ( Fc + ( Vc * q ) )
= ( 0.65 * 12000 ) - ( 10,000 + ( 0.25 * 12000 )
= -$5200
