In the coordinate plane, a rectangle has vertices at \(A(0, 0)\), \(B(8, 0)\), \(C(8, 5)\), and \(D(0, 5)\). The rectangle is then scaled up by a factor of \(1.5\) about the origin. Calculate the area of the scaled rectangle and the cost to cover this new area if the cost is $2.50 per square unit. Express your final answer as a monetary value. Let's think step by step and output the final answer within \boxed{}.
