Okay, so we inherit $18 ,750, and we're going to invest part of it at 12 % interest, and another part of that, or basically the rest of that, at 10%.
00:18
So we can say let x equal the amount of money invested, at 12%.
00:40
Okay, and then that would mean that the rest of it, which is going to be 18 ,750 minus x is invested at 10%.
01:09
Okay, then we can put it together an equation, so we're told that you end up with an interest accrued.
01:24
Of $2 ,117.
01:30
So in order to get that $2 ,117, you had x times, so to do a percentage we would say 0 .12, it's converted to a decimal, 0 .12.
01:51
So we got 12 % of what we invested at that rate, plus 10 % of what we invested at the rest of what we invested.
02:11
So that was the 18 ,750 minus x.
02:19
And those two amounts were equal to 21117.
02:25
So we can solve for x to figure out what amount we invested at 12%.
02:32
And then use 18 ,750 minus x to figure out how much was invested at 10%.
02:41
All right, so the first thing we'll do is just distribute this point one zero.
02:48
Okay, so we'll just leave this alone for a second...
