PLEASE HELP MEE!!!!! BRAINLIEST & 50 POINTS

Answer 1

Step-by-step explanation:

Looking at the matrix, they state that b1 and b2 are the costs per pound of bok choy at Market 1 and Market 2.  While r1 and r2 are the costs per pound of rice flour at Market 1 and Market 2.  

$\left[\begin{array}{ccc}0.5&0.5\end{array}\right] \left[\begin{array}{ccc}b_1&r_1\\b_2&r_2\end{array}\right] =\left[\begin{array}{ccc}p&q\end{array}\right]$

$\left[\begin{array}{ccc}\frac{b_1}{2}+\frac{b_2}{2}&\frac{r_1}{2}+\frac{r_2}{2}\end{array}\right]=\left[\begin{array}{ccc}p&q\end{array}\right]$

Therefore, $q = \frac{r_1}{2}+\frac{r_2}{2}$

So we can see that we are looking for the total cost of a half-pound of rice flour at market 1 and a half-pound of rice flour at market two.

Answer:  Option J

Answer 2

Let's see

$\sf [0.5\:0.5]\left[\begin{array}{cc}\sf b_1 &\sf r_1\\ \sf b_2&\sf r_2\end{array}\right]$

• b1 and b2 are markets

r_1 and r2 are costs per pound

So

• It's r_1 is the cost of 1/2 pound rice at market one and r_2 is at market 2

Option J
