00:01
So, according to the question, we invest $5000 in total.
00:05
Okay.
00:05
So, we put or we invest $5000 in total.
00:16
So, if we suppose that if we put x dollars in 3 % account, then we will put $5000 minus x dollars in 6 % account.
00:40
Okay.
00:41
So, we can write then, then we put $5000 minus x dollars.
00:51
Okay.
00:52
Because the total invested amount is $5000.
00:55
So, if we put x dollars in 3 % account, then we have to put $5000 minus x dollars in 6 % account.
01:02
Okay.
01:05
So, the total interest is $220.
01:09
We know the formula of interest i is equal to p r t, where p is the principal investment, r is the rate in decimal form and t is the time.
01:19
Okay.
01:19
So, the total interest is $220.
01:22
So, we write here 220.
01:24
And the principal in the first 3 % rate case is x multiplied by rate in decimal form is 0 .03 and time is 1 year.
01:34
So, 1 plus in the second case, the rate is 6%.
01:39
So, decimal form will be 0 .06 and principal is 5000 minus x multiplied by 0 .06 multiplied by 1.
01:49
Okay...
