For finding the solution, you want to sum the revenue from each class of paying customers. There were 92-40 who were over 12 years and paid $48, so the revenue from those folks is (92-40)·48. This term is found in the first and last selections only.

There were 40-x customers who were in the age range 3–12 years, so paid $36 each. The revenue from them is (40-x)·36. This term is found in the last selection only.

suppose that a severe virus in impacting a bee colony and the population of bees has a half life of 5 days What percentage of th

BartSMP [9]

So we want to know what percentage of bees would survive a virus after 19 days of decay if the bee population has a half life of 5 days. So every 5 days 50% of bees die. Lets say that N is the number of bees before the virus. So after 5 days is 50% less bees, so 50% of N remains. After another 5 days again, 50% bees die, and 50% out of 50% is 25%. So after 10 days, 25% of bees remain or 25%N or 0.25*N. After another 5 days its 12.5 % of bees remain or 0.125*N. And after 4 days 40% more bees die. And that is 0.4*0.125*N = 0.05N. 0.05*100% is 5%. So after 19 days, 5% of bees remain and 95% of bees is dead.
