Howie Jones used the following information to calculate the profit coefficients for Aqua-Spas and Hydro-Luxes: pumps cost $225 each, labor costs $12 per hour, tubing costs $2 per foot. In addition to pumps, labor, and tubing, the production of Aqua-Spas and Hydro-Luxes consumes, respectively, $243 and $246 per unit in Howie Jones used the following information to calculate the profit coefficients for Aqua-Spas and Hydro-Luxes: pumps cost $225 each, labor costs $12 per hour, tubing costs $2 per foot.
