Ron will not make his monthly goal of $1,270 and will need $741.68 to supplement his monthly income when he retires.
Answer:
$3,900
Explanation:
A speed boat bought for $13,000 depreciates at 10% per annum compounded continuously. What is its value after 7 years?
Round the answer to nearest dollar.
Amount of depreciation per annum = 13,000 x 10% = $1,300
Amount of depreciation in 7 years = 1,300 x 7 = $9,100
Value of Speed boat after 7 years = 13,000 - 9,100 = $3,900
Simple interest formula
I=PRT
I=interest
P=principal=amount invested
R=rate in decimal
T=time in years
we are given
P=1750
R=1.9%=0.019
T=1
I=PRT
I=(1750)(0.019)(1)
I=33.25
that's how much interest
total will be $1750+interest=$1750+$33.25=$1783.25
your answer is right
Answer:
A
Explanation:
Optimization using total value calculates the total value of each feasible option and then picks the option with the highest total value.
Optimization using marginal analysis calculates the change in total value when a person switches from one feasible option to another, and the uses these marginal comparisons to choose the option with the highest total value.
Both gives identical answers.
Optimization can be implemented using many different techniques.
One of it, is Total value total benefit - total cost (net benefit).
It translate all cost and benefits into common units, like dollar per month.
Calculate the total net benefit of each alternative.
Pick the alternative with the highest net benefit.
