Chapter 8.7, Problem 76STP

(a)

To determine

To find: The Inventory matrix and cost matrix of each item.

Answer to Problem 76STP

The inventory matrix is $\left[\begin{array}{cccc}15& 25& 45& 60\end{array}\right]$ and the cost matrix is $\left[\begin{array}{c}60\\ 40\\ 25\\ 5\end{array}\right]$ .

Explanation of Solution

Given information:

The given cost is large afghans $60\$$ , baby blankets is $40\$$ , doilies is $25\$$ and pot holders is $5\$$ .

INVENTORY The given inventory cost is large afghans $12\$$ , baby blankets is $25\$$ , doilies is $45\$$ and pot holders is $50\$$ .

Calculation:

The inventory matrix for the no. of each item is :

  $\left[\begin{array}{cccc}15& 25& 45& 60\end{array}\right]$

The cost matrix is

  $\left[\begin{array}{c}60\\ 40\\ 25\\ 5\end{array}\right]$

Therefore, the inventory matrix is $\left[\begin{array}{cccc}15& 25& 45& 60\end{array}\right]$ and the cost matrix is $\left[\begin{array}{c}60\\ 40\\ 25\\ 5\end{array}\right]$ .

(b)

To determine

To find: The matrix of total income.

Answer to Problem 76STP

The matrix of total income is $\left[\begin{array}{cccc}15& 25& 45& 60\end{array}\right]\left[\begin{array}{c}60\\ 40\\ 25\\ 5\end{array}\right]$ .

Explanation of Solution

Given information:

The given cost is large afghans $60\$$ , baby blankets is $40\$$ , doilies is $25\$$ and pot holders is $5\$$ .

INVENTORY The given inventory cost is large afghans $12\$$ , baby blankets is $25\$$ , doilies is $45\$$ and pot holders is $50\$$ .

Calculation:

Consider all items are sold.

Therefore, the matrix of total income is. $\left[\begin{array}{cccc}15& 25& 45& 60\end{array}\right]\left[\begin{array}{c}60\\ 40\\ 25\\ 5\end{array}\right]$
