Assume that MTA Sandwiches sells sandwiches for $2.85 each. The cost of each sandwich follows:

mixas84 [53]

Answer:

a. profit is lower

b. lowest price $2.29

Step-by-step explanation:

a. We have to analyze how this especial order affect the profit of the company

Profit = Revenue- Total cost = P(x) =(Px * Q)-(FC + vc*Q)

Regular production profit= $2.85 x 18,400 units -$2.60 x 18,400 units=

Regular production profit=4600

Production with special order= (P1 * Q1)+(P2 * Q2)-(FC + vc*Q)

P2= price of special order

Q2= quantity of special order

Q= Q1 +Q2

Production with special order= (P1 * Q1)+(P2 * Q2)-(FC + vc*Q)= $2.85 x 18,400 units +$1.85 x 800 units - $18,400- $1.60 x 19600=

Production with special order= 51888 +1480- $18,400- 30720

Production with special order= 4.248‬

b.Production with special order= (P1 * Q1)+(P2 * Q2)-(FC + vc*Q) =4600

=51888 +(P2 * 800)- $18,400- 30720 =4600

=(P2 * 800)= 4600- 51888 + $18,400+30720

P2=1.832/800 = 2,29

Answer:

Step-by-step explanation:

$CI=\left[\begin{array}{ccc}1&6&0\\0&1&2\\1&-1&3\end{array}\right] \left[\begin{array}{ccc}1&0&0\\0&1&0\\0&0&1\end{array}\right]$

Subtract row 3 from row 1:

$\left[\begin{array}{ccc}1&6&0\\0&1&2\\0&7&-3\end{array}\right] \left[\begin{array}{ccc}1&0&0\\0&1&0\\1&0&-1\end{array}\right]$

Subtract row 3 from 7 times row 2:

$\left[\begin{array}{ccc}1&6&0\\0&1&2\\0&0&17\end{array}\right] \left[\begin{array}{ccc}1&0&0\\0&1&0\\-1&7&1\end{array}\right]$

Divide row 3 by 17:

$\left[\begin{array}{ccc}1&6&0\\0&1&2\\0&0&1\end{array}\right] \left[\begin{array}{ccc}1&0&0\\0&1&0\\\frac{-1}{17} &\frac{7}{17} &\frac{1}{17} \end{array}\right]$

Subtract 2 of row 3 from row 2:

$\left[\begin{array}{ccc}1&6&0\\0&1&0\\0&0&1\end{array}\right] \left[\begin{array}{ccc}1&0&0\\\frac{2}{17} &\frac{3}{17} &\frac{-2}{17} \\\frac{-1}{17} &\frac{7}{17} &\frac{1}{17} \end{array}\right]$

Subtract 6 of row 2 from row 1:

$\left[\begin{array}{ccc}1&0&0\\0&1&0\\0&0&1\end{array}\right] \left[\begin{array}{ccc}\frac{5}{17}&\frac{-18}{17}&\frac{12}{17}\\\frac{2}{17} &\frac{3}{17} &\frac{-2}{17} \\\frac{-1}{17} &\frac{7}{17} &\frac{1}{17} \end{array}\right]$

$C^{-1}=\frac{1}{17} \left[\begin{array}{ccc}5&-18&12\\2&3&-2\\-1&7&1\end{array}\right]$

$C^{-1}b=\frac{1}{17} \left[\begin{array}{ccc}5&-18&12\\2&3&-2\\-1&7&1\end{array}\right]\left[\begin{array}{c}10&1&3\end{array}\right]=\left[\begin{array}{c}4&1&0\end{array}\right]$
