CVP Analysis; Sensitivity Analysis; Multiple Products GoGo Juice is a combination gas station and convenience store located at a busy intersection. Recently a national chain opened a similar store only a block away; consequently, sales have decreased for GoGo. In an effort to reclaim lost sales, GoGo has implemented a promotional effort; for every $10 purchase at GoGo, the customer receives a Sl coupon that can be redeemed toward the purchase of gasoline. The average gasoline customer purchases 15 gallons of gasoline at $2.50/gal. The results of an average month, prior to this coupon promotion, are shown below.

Not included in the information presented below is the monthly cost of printing the coupons, which is estimated to be $500. Coupons are issued on the basis of total purchases regardless of whether the purchases are paid in cash or paid by redeeming coupons. Assume that coupons are distributed to customers for 75% of the total sales. Also assume that all coupons distributed are used to purchase gasoline.

Sales Cost of Sales (per or % of retail)
Gasoline $100,000 $1.875 per gallon
Food and beverages 60,000 60%
Other products 40,000 50%

Other Cost
Labor—station attendants $10,000
Labor—supervision 2,500
Rent. power, supplies, interest, and misc. 40,000
Depreciation (pumps, computers, counters, fixtures, and building) 7,500

Required:
a. If GoGo Juice implements the promotional coupon effort, calculate the profit (loss) before tax if the sales volume remains constant and the coupons are used to purchase gasoline. Assume the sales mix remains constant. Prepare a contribution income statement to support your answer.
b. Calculate the breakeven sales (in dollars) for GoGo Juice if the promotional effort is implemented. Assume that the product mix remains constant. Use the weighted-average contribution margin ratio approach to generate your answer. (Hint: Sales mix for this purpose is defined on the basis of relative sales dollars, not units.)
c. Based on the assumed sales mix (determined on the basis of relative sales dollars, not units), determine the composition of total breakeven sales dollars across the three product lines: gas; food and beverages; and other products.
d. Disregarding your responses to requirements 1 and 2, assume the weighted-average contribution margin ratio, after implementation of the coupon program, is 35 percent. Calculate the before tax profit (loss) for GoGo Juice, assuming sales increase 20 percent due to the new program. Assume that the sales mix in terms of relative sales dollars remains constant.
e. GoGo Juice is considering using sensitivity analysis in combination with cost-volume-profit (CVP) analysis. Discuss the use of sensitivity analysis in conjunction with CVP analysis. Include in your discussion at least three factors that make sensitivity analysis prevalent in decision making.
f. Provide a brief description of the methods that can be used to deal with uncertainty.
