Answer: Proposal C
Explanation:
The way to solve this is to calculate the Present Values of all these payments. The smallest present value is the best.
Proposal A.
Periodic payment of $2,000 makes this an annuity.
Present value of Annuity = Annuity * ( 1 - ( 1 + r ) ^ -n)/r
= 2,000 * (1 - (1 + 0.5%)⁻⁶⁰) / 0.5%
= $103,451.12
Proposal B
Present value = Down payment + present value of annuity
= 10,000 + [2,200 * ( 1 - ( 1 + 0.5%)⁻⁴⁸) / 0.5%]
= 10,000 + 93,676.70
= $103,676.70
Proposal C
Present value = Present value of annuity + Present value of future payment
= [500 * (1 - (1 + 0.5%)⁻³⁶) / 0.5%] + [116,000 / (1 + 0.5%)⁶⁰]
= 16,435.51 + 85,999.17
= $102,434.68
<em>Proposal C has the lowest present value and so is best. </em>
Answer: B - a general improvement in technology affecting production of all goods
Explanation: The Production Possibility Frontier is a curve that shows the two combination of goods an economy can produce when all its factors of production are efficiently used.
Technological progress shifts the curve outward, away from the origin as more output would be produced using the same combination of factor inputs.
Shifting of resources from butter to gun would lead to movements along the curve as more gun would be produced and less butter.
Pacifism becoming less popular which increases gun production, would cause movement along the curve.
Increase in consumer desire for butter increase the amount of butter produced . This would generate a movement along the curve
