Ok, here we are compounding continuously.
00:05
And here's the formula for doing that.
00:08
A, the end amount, p, starting amount, e, r, the interest rate in decimal form.
00:16
So here then, 5 % will be 0 .05.
00:20
That's the r value.
00:22
T, number of years.
00:24
So a then is basically pert, p -e -r -t.
00:30
Now, p must double.
00:34
So 8 ,000 becomes 16 ,000.
00:39
That's the end amount.
00:40
Starting amount, 8 ,000.
00:43
E, r, 0 .05.
00:48
And t, i want to find...
