With help from the marketing department, engineers at Joes Shop have designed a new type of cable modem that is easier to install in computers and more reliable than any cable modems currently in use. The marketing managers want to differentiate it from less sophisticated products made by Joes Shop. An important part of this effort is likely to be the selection of a for the new modem.

The amount of short term note is $100,000 and long term note is $80,000 respectively.

Explanation:

For computing the amount of each unit we have to assume the things which is shown below:

Let us assume the short term note be X which equal to 10 %

And, the long term note be $180,000 - X which is equal to 7%

So, the equation would be

0.10X + 0.07 ( $180,000 - X) = $15,600

0.10X + $12,600 - 0.07X = $15,600

0.03X = $15,600 - $12,600

0.03X = $3,000

X = $3,000 ÷ 0.03

X = $100,000

So, the short term note is $100,000

And, the long term note is = $180,000 - $100,000 = $80,000

Hence, the amount of short term note is $100,000 and long term note is $80,000 respectively.
