Okay, so we have fund a and that pays a 4 % return and then fund b is a 10 % return.
00:15
And we have $5 ,000 total to invest.
00:21
So in question 15, we're going to put everything in fund a.
00:27
So we want to know how much are we making on our investment.
00:31
So we want to know what's 4 % of $5 ,000.
00:36
So that's 0 .04 times $5 ,000.
00:42
We're going to expect to make $200 in a year.
00:51
Now, 16, we want to make $355.
00:58
So we're going to put part in each fund.
01:01
So i'm going to let x equal the amount in fund a, which means $5 ,000 minus x will be the amount in fund b...
