Problem 19-5 (Algo) A retired couple supplement their income by making fruit pies, which they sell to a local grocery store. During the month of September, they produce apple and grape pies. The apple pies are sold for $2.00 to the grocer, and the grape pies are sold for $4.00. The couple is able to sell all of the pies they produce owing to their high quality. They use fresh ingredients. Flour and sugar are purchased once each month. For the month of September, they have 2,400 cups of sugar and 3,300 cups of flour. Each apple pie requires 1½ cups of sugar and 3 cups of flour, and each grape pie requires 2 cups of sugar and 3 cups of flour. a. Determine the number of grape and the number of apple pies that will maximize revenues if the couple working together can make an apple pie in 6 minutes and a grape pie in 3 minutes. They plan to work no more than 60 hours. (Round your answers to nearest whole number.) Apple Grape Revenue Pies Pies b. Determine the amounts of sugar, flour, and time that will be unused. (Leave no cells blank - be certain to enter "0" wherever required. Round your intermediate calculations and final answers to the nearest whole number.)

Write the answers as a fraction in reduced form.Do you know what regifting is? It is loosely defined as "giving someone a gift that was originally given to you without telling the recipient the origin of the gift." Now that you know, how often do you engage in regifting? In a survey of 5555 persons, the answers to that question were as follows. Response to the question: How often do you engage in regifting?Very often → 146 votesEvery now and then → 819 votesNot very often → 1756 votesNever → 2808 votesI'm not sure → 26 votesCurrent number of voters: 5555 If one of the persons is selected at random, what is the empirical probability of the following? (a) The person very often engages in regifting. (b) The person never engages in regifting.(c) If you get a gift and you assume that the results of the survey apply to that gift, what is the probability that you are getting a regift? Assume that the people who give regifts are the ones that did not answer "Never."
