In one month, Mikhail’s Furnishings can make 160 carpets or 160 quilts, while Dominique’s Parlor can make 120 carpets or 200 qui
marysya [2.9K]

Answer:

Step-by-step explanation:

Mikhail’s Furnishings: 160 carpets or 160 quilts

Dominique’s Parlor:  120 carpets or 200 quilts

<u>Current production per month</u>

Mikhail’s: 80 carpets and 80 quilts

Dominique’s: 60 carpets and 100 quilts

<u>Post-trade</u>

Mikhail’s: produces 160 carpets

Dominique’s: produces 200 quilts

They trade 90 quilts for 70 carpets so at the end of trade they will have items as follows

Mikhail’s carpets will reduce from 160-70=90 carpets but have additional 70 quilts

Dominique’s quilts will reduce  from 200-90=110 but have additional  carpets of 70

<u>Gains from trade</u>

Comparing outcome of post-trade with current production

Mikhail’s Furnishings: 90 carpets-80 carpets=10 carpets

                                  90 quilts-80 quilts=10 quilts

Dominique’s Parlor: 70 carpets -60 carpets=10 carpets

                                110  quilts-100 quilts=10 quilts

A bank wishes to invest a $100, 000 trust fund in three sources: bonds paying 8%; certificates of deposit paying 7%; and first m
Nuetrik [128]

Answer:

It is not possible to make the investment under the given conditions.

Step-by-step explanation:

Let x, y and z be the amounts invested in bonds, certificates of deposit and mortgages respectively.

<u>1st equation </u>

<em>“A bank wishes to invest a $100, 000 trust fund in three sources” </em>

x + y + z = 100,000

<u>2nd equation </u>

<em>“The bank wishes to realize an $8, 000, annual income from the investment and bonds paying 8%; certificates of deposit paying 7%; and first mortgages paying 10%” </em>

<em> </em>

0.8x + 0.7y + 0.1z = 8,000

3rd equation

<em>“the total amount invested in bonds and certificates of deposit must be triple the amount invested in mortgages” </em>

<em> </em>

x+y = 3z

and we have a <em>linear system of 3 equations with 3 unknowns </em>

    x +      y +      z = 100,000

0.8x + 0.7y + 0.1z = 8,000

    x +      y      -3z = 0

This system has a unique solution given by

x = -470,000  

y = 545,000

z = 25,000

Since x is negative, we deduct there is no way to do such an investment.
