I'll do it both ways since you do not specify whether it is simple of compound interest. FV = P + PRT
10000 = P + P(.03)(20)
10000 = P(1 + 0.60)
10000 = 1.6P
6250 = P
Check
6250 * .03 * 20 = 3750 + 6250 = 10000 ◄
FV = P + P(1+R)T
10000 = P + P(1.03)20
10000 = P + P(1.80611)
10000 = 2.80611*P
3563.65 = P
Check
3563.25 + 3563.25(1.03)20
3563.25 + 3563.25*1.80611
3563.25 + 6436.35

To calculate the interest gained on something, a simple formula is used. Initial value x (percentage increase as a decimal)^years So: 10000 x 1.05^15 = 20789.28 (2d.p).
The monthly interest is 100.
Using the compound interest formula which states A = P (1 + r/n)nt. We get the following result:10000 ( 1 + .095/4)4(4)10000 (1 + 0.02375) 1610000 (1.02375) 1610000 (1.45580)$14558Therefore you earn approximately $4558.00 on a CD yielding a 9.5% interest rate for 4 years.
An average of 321.56
V = 10000*(1.05)20 = 26532.98 dollars
In two years, the value of 10,000 dollars with 3.78 interest would be 10,770.29 dollars. An increase 770.29 dollars would be realized.
The future value (FV) of $10,000 at 5% interest for 7 years follows the following formula: 10,000 (1+.05)^7 = 10,000 * 1.41 = $14,100
$14,693.28
10000*70/100 = 7000 dollars.
The value today, of 10,000 dollars from 1948 will be about 99,500 dollars. This is estimated at an interest rate of three and a half percent.
2000 dollars
16% of 10000 = 10000*16/100 = 1600 dollars
3000
$1500
With only one year the value is 11600
40% = 40/100 = 0.4now 40 percent of 10000 is 0.4x10000 = 4000dollars
