Answer:
$4,900 (From simple interest method)
Explanation:
Given:
Amount invested (p) = $4,000
Interest rate for simple interest (r) = 4.5% = 4.5/100 = 0.045
Interest rate for Compound interest (i) = 4%
Number of year (t) = 5
Computation of amount from simple interest method:
Amount = p(1+rt)
Amount = $4,000[1+(0.045 × 5)]
Amount = $4,000[1+0.225]
Amount = $4,000[1.225]
Amount (from simple interest method) = $4,900
Computation of amount from compound interest method:
Therefore, Amount from simple interest method is higher .
Answer:
a) - r=5%:
- r=4%:
- r=3%:
b) - r=5%: t=14 years
- r=4%: t=17 years [/tex]
- r=3%: t=23 years [/tex]
c) The amount obtained is
- Compuonded quarterly: $5,191.83
- Compuonded continously: $5,200.71
The latter is always greater, since the more often it is capitalized, the greater the effect of compound interest and the greater the capital that ends up accumulating.
Explanation:
The rate of accumulation of money is
To calculate the amount of money accumulted in a period, we have to rearrange and integrate:
When t=0, S=S₀ (the initial capital).
Now we have the equation for the capital in function of time:
a) For an initial capital of $4000 and for a period of five years, the amount of capital accumulated for this interest rates is:
- r=5%:
- r=4%:
- r=3%:
b) We can express this as
- r=5%:
- r=4%:
- r=3%:
c) When the interest is compuonded quarterly, the anual period is divided by 4. In 5 years, there are 4*5=20 periods of capitalization. The annual rate r=0.0525 to calculate the interest is also divided by 4:
If compuonded continously, we have:
The amount obtained is
- Compuonded quarterly: $5,191.83
- Compuonded continously: $5,200.71
The latter is always greater, since the more often it is capitalized, the greater the effect of compound interest and the greater the capital that ends up accumulating.
