The O’Toole’s leave their house in Canada to vacation in Mexico for a week over winter break. In their

Question

absence, their house receives an average of 8 inches of snow per day each day during the seven-day
period. However, the average air temperature rises above 32 degrees Fahrenheit for a few hours each day
causing .25" of snow to melt by the end of each day. By the end of the seven days, the height of the snow
accumulation on the ground has been reduced by 20% due to compaction. Which method should be used
to correctly calculate the height of the snow buildup in the Hill’s yard that they find when they return from
vacation?

7 * 8 = 56 inches

7 * 0.25 = 1.75

56 - 1.75 = 54.25

54.25 * 0.8 = ?
