[The following information applies to the questions displayed below.] Camp Rainbow offers overnight summer camp programs for children ages 10-14 every summer during June and July. Each camp session is one week and can accommodate up to 200 children. The camp is not coed, so boys attend during the odd-numbered weeks and girls attend during the even-numbered weeks. While at the camp, participants make crafts, participate in various sports, help care for the camp's resident animals, have cookouts and hayrides, and help assemble toys for local underprivileged children. The camp provides all food as well as materials for all craft classes and the toys to be assembled. One cabin can accommodate up to 10 children, and one camp counselor is assigned to each cabin. Three camp managers are on-site regardless of the number of campers enrolled. The results of the least-squares regression of the number of campers and the cost to run camp are given below. Following is the cost information for Camp Rainbow's operations last summer: Number of Cost to Run Week Campers Camp 1 90 $8,050 2 118 8,460 3 156 10,900 4 174 11,100 5 188 13,670 6 184 14,300 7 170 12,325 8 156 11,270 Intercept X Variable 1 Coefficients 1876.55 60.73 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?
