Answer:
Step-by-step explanation:
RT × TS = PT × TQ
Answer:
(a) $7492
(b) $10,253
(c) $14,032
Step-by-step explanation:
As we know, the final Amount can be calculated with the formula for compound interest,
A = P(1 + \frac{r}{n} )^{nt}
where,
A = Final Amount due
P = Initial principal amount borrowed
r = rate of interest in decimal
n = number of times applied per time period
t = total time period
Now, according to the given data,
(a) in 4 years ;-
⇒ ![A = 4000(1 + \frac{0.16}{4} )^{4(4)}](https://tex.z-dn.net/?f=A%20%3D%204000%281%20%2B%20%5Cfrac%7B0.16%7D%7B4%7D%20%29%5E%7B4%284%29%7D)
⇒ ![A = 7492](https://tex.z-dn.net/?f=A%20%3D%207492)
(b) in 6 years ;-
⇒ ![A = 4000(1 + \frac{0.16}{4} )^{4(6)}](https://tex.z-dn.net/?f=A%20%3D%204000%281%20%2B%20%5Cfrac%7B0.16%7D%7B4%7D%20%29%5E%7B4%286%29%7D)
⇒ ![A = 10,253](https://tex.z-dn.net/?f=A%20%3D%2010%2C253)
(c) in 8 years ;-
⇒ ![A = 4000(1 + \frac{0.16}{4} )^{4(8)}](https://tex.z-dn.net/?f=A%20%3D%204000%281%20%2B%20%5Cfrac%7B0.16%7D%7B4%7D%20%29%5E%7B4%288%29%7D)
⇒ ![A = 14,032](https://tex.z-dn.net/?f=A%20%3D%2014%2C032)
931 are the answer ................
117,150
5% of 71,000 is 3,550, 3,550 c 13(years) = 46,150(what the company will add to his salary) 71,000 + 46,150 = 117,150
