All of the current calculations for numbers 1 and 2 are correct. I need help on number 3 to prepare a scattergraph using the data given. Thanks

The Lakeshore Hotel's guest-days of occupancy and custodial supplies expense over the last seven months were: Custodial Guest-Days of Supplies Month March April May June July August 4,000 6,500 10,500 12,000 9,000 7,500 $ 7,500 S 8,250 S 10,500 S 12,000 S 13,500 S 10,750 S 9,750 Guest-days is a measure of the overall activity at the hotel. For example, a guest who stays at the hotel for three days is counted as three guest-days. ired: g the high-low method, estimate a cost formula for custodial supplies expense. (Do not round your intermediate calculations and Round the Variable cost per guest day to 2 decimal points) Guest-Days Supplies Expense High activity level Low activity level Change 2,000 S 4,000 8,000 S 13,500 7,500 6,000 Variable cost per guest-day Fixed cost per month S 0.75 per guest-day S 4.500 2. Using the cost formula you derived above, what amount of custodial supplies expense would you expect to be incurred at an occupancy level of 11,000 guest-days? (Do not round your intermediate calculations.) Variable cost Fixed cost Total cost 12.750
