Question 1094799
A bank loaned out ​$18000, part of it at the rate of 6% per year and the rest at 14% per year. If the interest received in one year totaled ​$2000, how much was loaned at 6% ?
<pre>Let the 6% loan amount be S
Then the 14% loan amount = 18,000 - S
We then get: .06S + .14(18,000 - S) = 2,000
.06S + 2,520 - .14S = 2,000
.06S - .14S = 2,000 - 2,520
- .08S = - 520
S, or 6% loan amount = {{{highlight_green(matrix(1,3, (- 520)/(- .08), "=", "$6,500"))}}}
That's all!! Nothing COMPLEX and/or CONFUSING!
