Answer:
Let ![A=\left[\begin{array}{ccc}a_{11}&a_{12}&a_{13}\\a_{21}&a_{22}&a_{23}\\a_{31}&a_{32}&a_{33}\\a_{41}&a_{42}&a_{43}\end{array}\right]](https://tex.z-dn.net/?f=A%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7Da_%7B11%7D%26a_%7B12%7D%26a_%7B13%7D%5C%5Ca_%7B21%7D%26a_%7B22%7D%26a_%7B23%7D%5C%5Ca_%7B31%7D%26a_%7B32%7D%26a_%7B33%7D%5C%5Ca_%7B41%7D%26a_%7B42%7D%26a_%7B43%7D%5Cend%7Barray%7D%5Cright%5D)
the matrix associated to the system and
![b=\left[\begin{array}{ccc}\alpha_{1}\\\alpha_{2}\\\alpha_{3}\\\alpha_4\end{array}\right]](https://tex.z-dn.net/?f=b%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D%5Calpha_%7B1%7D%5C%5C%5Calpha_%7B2%7D%5C%5C%5Calpha_%7B3%7D%5C%5C%5Calpha_4%5Cend%7Barray%7D%5Cright%5D)
the vector of constant values of the system.
The equation of the line joining p and q is
. Since p and q are solutions of the linear system then, 
and 
Let 
. Observe that 
. Then w is a solution of the homogeneous system Ax=0.
Now, let s=p+r(q-p) for some 
be a point in the line joining p and q. Observe that
Then As=b. This means that s is a solution of the linear system.
For 10% coupon, 10% of the original price is decreased, therefore we can multiply the price by (1-10%)=90% to find the total cost:
24×90%
= 24×0.9
= $21.9
Therefore the answer is $21.9.

Answer:
726
Step-by-step explanation:
Here p = k / q², and 24 = k / 121, or k = 2904
Then p = 2904 / q²
If q = 2, p = 2904 /4 = 726
