3. a. The Morosco Hotel and Casino in the older part of Las Vegas had bodgeted sales of 900 room-nights during this past week, at an average room rate of $350 room per night. In actial fact, the hotel sold only 820 room-nights, but at an average rate of $375/ room per night. Please calculate the overall variance from budget in room sales (and remember that a variance requires a dollar figure AND the appropriate letter). Then split the variance into a Price Variance and a Volume Variance, showing that the two of them together make up the overall variance. b. During that same week at Morosco, housekeeping costs had been budgeted at $7.45 per room. with an expected 900 rooms to clean up. Actual housckeeping costs were $7.10 per room, but of course there were 820 rooms to clean, not 900 . Calculate the overall variance from budget for housekeeping costs, then split it up into a Cost Variance and a Volume Variance, showing that the two of them together make up the overall variance
