1.Management is concerned about the losses experienced during the spring and would like to know more about the cost behaviour. Develop a cost equation for each of the costs.(Do not round intermediate calculations. Round "Per Unit" answers to 2 decimal places.)

2. Assume that fixed costs are incurred uniformly throughout the year. Compute the annual break-even sales, and the profit if 74,000 units are sold during the year.(Round "Break-even sales" answer to nearest whole number.)
