Need help and explanation please. in a dumbed down version

Niquelle has $72 to spend on movie tickets and basketball games. . If movie tickets cost $12 each and it costs $18 to see a basketball game, list all the consumption bundles that Niquelle can purchase with her budget of $72. (List only the consumption bundles that completely use up her budget.) Draw Niquelle's budget line for movies and basketball games. Suppose the price of movie tickets rises to $24 each. Draw the new budget line on your graph from part b. If Niquelle's budget remains at $72, movie tickets are $12, as in part b, but basketball ticket prices fall to $9, draw her new budget line on your graph from part b. . How will the original budget line change if Niquelle's budget decreases to $36? Draw this new budget line. Each week, Ahmed sets aside $18 to be used to buy either doughnuts or bagels. . If the price of a doughnut is $3, and the price a bagel is $6, list all the consumption bundles that Ahmed can afford, with his budget. (List only the consumption bundles that completely use up his budget.) Given the following information about Ahmed's utility from consuming doughnuts and bagels, calculate his marginal utility and his marginal utility per dollar, and fill in the following tables: Doughnuts Total Utility Marginal Utility Marginal Utility per Dollar 0 0 1 18 2 30 3 39 4 45 5 48 6 48 Bagels Total Utility Marginal Utility Marginal Utility per Dollar 0 0 1 42 2 66 78 Use your answers from question two above to answer the following questions. . Does Ahmed have diminishing marginal utility when consuming doughnuts? Does he have diminishing marginal utility from consuming bagels? What does diminishing marginal utility mean? Using the marginal utility per dollar that you calculated in question two, explain why two bagels and two doughnuts is the consumption bundle that will give Ahmed the most total utility. Calculate the total utility that Ahmed will receive from each of the consumption bundles in part a, from question two
