In this situation, we're going to use the formula for percentage increase over amount of time.
00:07
And that formula is that the future amount, let's call it f, the future amount of anything, is the present value times 1 plus the rate of increase and multiply by the time, the number of times that it happens.
00:23
So in this case, we have two coins, and we want to know what the expected value of the two coins from now.
00:30
So it says that you have two coins that each is valued at $100.
00:35
So the future value of both coins, of both coins, of the two of them, is going to be the value of one, right now, one, or 100, plus one plus the rate of increase, which is 5 .2%, but you've got to write that in decimal form...
