Lifemaster produces two types of exercise treadmills: regular and deluxe. The

exercise craze is such that Lifemaster could use all its available machine hours to

produce either model. The two models are processed through the same production

departments. Data for both models is as follows:

Requirements

1. What is the constraint?

2. Which model should Lifemaster produce? (Hint: Use the allocation of fixed

manufacturing overhead to determine the proportion of machine hours used by

each product.)

3. If Lifemaster should produce both models, compute the mix that will maximize

operating income.
