Answer:
$2,800 was in the first account while $1,900 was in the second account
Step-by-step explanation:
Here, we want to know the amount of money in each account.
Let the amount in the first account be $x while the amount in the second account be $y
The addition of both gives $4,700
Mathematically;
x + y = 4700 ••••••••(i)
The amount of interest on first account is 14% = 14/100 * x = 14x/100
The amount of interest on second account is 11% = 11/100 * y = 11y/100
So the addition of both gives the total interest;
14x/100 + 11y/100 = 601
Multiply through by 100
14x + 11y = 60100 •••••••(ii)
From i, x = 4700-y
Substitute this into equation ii
14(4700-y) + 11y = 60100
65800 -14y + 11y = 60100
65800 -3y = 60100
3y = 65800 -60100
3y = 5700
y = 5700/3
y = 1900
Recall from substitution x = 4700 -y
x = 4700 -1900
x = 2800
