A bank loaned out $17,500, part of it at the rate of 10% annual interest, and the rest at 14% annual interest. The total interes
Gennadij [26K]

Answer:

<u>$7 000</u> was loaned at 10 % and

<u>$10 500</u> was loaned at 14 %

Step-by-step explanation:

                 Let x = amount loaned at 10 %

Then 17 500 - x = amount loaned at 14 %

                0.10x = interest on 10 % loan

0.14(17 500 - x) = interest on 14 % loan

          2170.00 = total interest

\begin{array}{rcl}0.10x + 0.14(17 500 - x) & = & 2170.00\\0.10x + 2450 - 0.14x & = & 2170.00\\2450 - 0.04x & = & 2170.00\\-0.04x & = & -280\\\\x & = & \dfrac{-280}{-0.04}\\\\x & = & \mathbf{7000}\\\\\end{array}

<u>$7000</u> was loaned at 10 % and

<u>$10 500</u> was loaned at 14 %

Check:

\\begin{array}{rcl}0.10\times 7000 + 0.14(17 500 - 7000) & = & 2170\\700 + 0.14(10 500) & = & 2170\\700 + 1470 & = & 2170\\2170 & = & 2170\\\end{array}

OK.
