Kristen estimates that, at her current rate of usage, the car will have zero resale value in five years, so the annual straight-line depreciation is $5,020. The car is kept in a garage for a monthly fee. Required: 1. Kristen drove the car 24,000 miles last year. Compute the average cost per mile of owning and operating the car. (Round your answers to 2 decimal places.) Average fixed cost per mile Variable operating cost per mile Average cost per mile Maria Lorenzi owns an ice cream stand that she operates during the summer months in West Yellowstone, Montana. She is unsure how to price her ice cream cones and has experimented with two prices in successive weeks during the busy August season. The number of people who entered the store was roughly the same each week. During the first week, she priced the cones at $5.80 and 2,460 cones were sold. During the second week, she priced the cones at $6.30 and 2,000 cones were sold. The variable cost of a cone is $1.50 and consists solely of the costs of the ice cream and the cone itself. The fixed expenses of the ice cream stand are $2,055 per week. Required: 1. What profit did Maria earn during the first week when her price was $5.80? 2. At the start of the second week, Maria increased her selling price by what percentage? What percentage did unit sales decrease? (Round your percentage answers to 2 decimal place.) 3. What profit did Maria earn during the second week when her price was $6.30? 4. What was Maria's increase (decrease) in profits from the first week to the second week
