Following is the cost information for Camp Rainbow's operations last summer: Suppose that Rainbow is contemplating staying open one additional week during the summer. Required: 1. Using the results of the least-squares regression analysis, determine Rainbow's contribution margin per camper if each camper pays $175 to attend the camp for a week. 2. Using the results of the least-squares regression analysis, prepare a contribution margin income statement for week 9 assuming Rainbow expects to have 170 campers that week. 3. Should Rainbow add a ninth week to its schedule? Complete this question by entering your answers in the tabs below. Using the results of the least-squares regression analysis, determine Rainbow's contribution margin per camper if each camper pays $175 to attend the camp for a week. Note: Do not round your intermediate calculations. Round your unit contribution margin and contribution margin ratio to two decimal places (f.e., 1234=12.34%.)
