Both questions below require a very indepth response with a real life example. At the current moment I am completely blank and desperately need the help. Please assist me. Thank you kindly.

How is the model of consumer choice different from the simple model of decision making. In what ways are the models of decision making similar? What are the marginal benefits and marginal costs for the consumer in deciding their optimal bundle? What role does the budget play in finding the optimal bundle?

Think of shopping at a grocery store. Describe how the model of consumer choice explains your thinking while shopping at a grocery store. Be sure to use the concepts of budget constraint, marginal utility, and marginal utility per dollar. If you do not think that it does describe your decision making, please say why.
