Answer:
$5,700 was invested in the 7% account
Step-by-step explanation:
Let the amount invested in 7% interest account be x while the other account is y
Total amount invested is &12,350
Thus:
x + y = 12,350 ••••(i)
interest on 7% = 7% of x = 7/100 * x = 7x/100
Interest on 6% = 6% of y = 6/100 * y = 6y/100
Since both have same interest;
7x/100 = 6y/100
7x = 6y
y = 7x/6
Put this into equation i
x + 7x/6 = 12,350
Multiply through by 6
6x + 7x = 74,100
13x = 74,100
x = 74,100/13 = $5,700
