Question

yummy yogurt sells three types of yogurt: nonfat, regular, and super creamy, at three locations. location i sells 60 gal of nonfat, 60 gal of regular, and 10 gal of super creamy each day. location ii sells 20 gal of nonfat, and location iii sells 70 gal of nonfat each day. daily sales of regular yogurt are 50 gal at location ii and 110 gal at location iii. at location i, 50 gal of super creamy are sold each day, and 20 gal of super creamy are sold each day at location iii.

b) the incomes per gallon for nonfat, regular, and super creamy are $13, $10, and $15, respectively. write a 1×3 or 3×1 matrix displaying the incomes. select the correct choice below and fill in the answer box to complete your choice.

a.

( type an integer or decimal for each matrix element. )

b.

( type an integer or decimal for each matrix element. )

Explanation:

Step1: Identify Matrix Type

We need a \(1 \times 3\) matrix for incomes (one row, three columns: nonfat, regular, super creamy). Incomes per gallon: nonfat \(\$13\), regular \(\$10\), super creamy \(\$15\).

Step2: Construct Matrix

The matrix will have elements \([13, 10, 15]\) as a \(1 \times 3\) matrix (Option B is likely the \(1 \times 3\) format, A is \(3 \times 1\) which is for gallons, not incomes). So the matrix is \(

$$\begin{bmatrix}13 & 10 & 15\end{bmatrix}$$

\).

Answer:

\(

$$\begin{bmatrix}13 & 10 & 15\end{bmatrix}$$

\) (corresponding to Option B's format)
