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
9999.70 (Rounding error) ◄

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).
Ten percent of 10,000 dollars is 1,000 dollars. This is calculated by multiplying 10,000 by 0.10 (which represents 10 percent). Therefore, 10 percent of 10,000 dollars equals 1,000 dollars.
The monthly interest is 100.
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.
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
5% of $10,000.00 = 5% * 10000 = 0.05 * 10000 = $500.00
