In economics an externality is the cost or benefit that affects someone who did not choose this. It is the true cost of a product that can be both positive or negative. Pollution can be an example of this. An educated labor force producing more is a positive example of this. The government rewards positive externality and punishes negative externality. Rewards can be surpluses and taxes can be punishments.

The formula is
A=p (1+r/k)^kt
A future value 12200
P present value 6100
R interest rate ?
K compounded quarterly 4
T time 9 years
Set the equation and solve for r (interest rate)
12200=6100 (1+r/4)^(4×9)
Divide both sides by 6100
12200/6100=(1+r/4)^(36)
2=(1+r/4)^(36)
Take the root of 36 for both sides
2^(1/36)=1+r/4
R= (2^(1/36)-1)×4
R=(2^(1÷36)−1)×4
R=0.0778×100
R=7.78%

Answer:
<u>Night Lights $ per unit 2.13</u>
<u>Desk Lamps $ per unit 8.50</u>
Explanation:
Determine total number of budgeted direct labour hours for the year
total number of budgeted direct labor hours for the year is calculated
= night lamp labor hours + desk lamp labor hours
= ( 60000 * 1/2 ) + ( 80000 * 2 )
= 30000 + 160000
= 190000
calculated the single plant wide factory overhead rate
factory overhead rate = total factory overhead / total number of budgeted unit
= 807500 / 190000
= 4.25 per labour hour
calculate factory overhead cost per each unit
night lamp = 4.25 * 1/2
= 2.13 per unit
desk lamp = 4.25 * 2
= 8.50 per unit
