Olivia has received a $15 gift certificate that is redeemable only for roasted peanuts. Bags of roasted peanuts come in two sizes, regular and jumbo. A regular bag contains 30 peanuts and a jumbo bag contains 50. A regular bag costs 50 cents and a jumbo bag costs 75 cents. Draw Olivia's budget constraint for regular and jumbo bags. Next assume that Olivia only cares about the number of peanuts, and not about the size of the bag. Draw her indifference curves. What will she choose? How do your answers change if a jumbo bag costs $1?
