A sporting goods store sells footballs, basketballs, and volleyballs. A football costs $19, a baskeball costs $19, and a volleyball costs $7. On a given day, 2 times the number of footballs sold was the same as the number of volleyballs sold. The store brought in a total of $3750 that day, and the money made from basketballs alone was $66 more than the money made from volleyballs alone. Let x, y, z be the number of footballs, basketballs, and volleyballs sold respectively. Set up the matrix A that solves Ax = b, where x = and 3750 b = 66 A =
