HW11: Problem 1 Previous Problem Problem List Next Problem (1 point) A sporting goods store sells footballs, basketballs, and volleyballs. A football costs $1, a baskeball costs $17, and a volleyball costs $ 31. On a given day, 6 times the number of footballs sold was the same as the number of volleyballs sold. They brought in a total of $3750 that day, and the money made from basketballs alone was $90 more than the money made from volleyballs alone. Let $x$, $y$, $z$ be the number of footballs, basketballs, and volleyballs sold respectively. Create the matrix $A$ that solves $Ax = b$, where $x = \begin{bmatrix} x \\ y \\ z \end{bmatrix}$ and $b = \begin{bmatrix} 3750 \\ 0 \\ 90 \end{bmatrix}$ $\begin{bmatrix} 17 & 31 & 25 \\ 5 & 0 & -1 \\ 0 & 31 & -25 \end{bmatrix}$
