B. if lucinda has only $60 to spend and the price of kewpie dolls and the price of beanie babies are both $12, how many of each will lucinda buy if she is rational?

Respuesta :

Lucinda Williams is back on the stage, and back singing after suffering a stroke at the end of 2020 that put some of her appearances and touring plans on hold. In May of 2021 after missing a scheduled appearance at Mile 0 Fest in Key West, Florida, Lucinda revealed she suffered a stroke in November.

4 Kewpie dolls, 4 Beanie babies.

If the price of Kewpie dolls and Beanie babies is $12, Lucinda will buy 4 of each.

b. 2 Kewpie dolls, 3 Beanie babies.

If Lucinda has only $60 to spend, and the price of both is $12, then her budget constraint is: 12x + 12y = 60

Here, x represents Kewpie dolls and y represents Beanie babies.

Lucinda will buy 3 units of Beanie babies and 2 units of Kewpie dolls. This conclusion is reached by buying according to decreasing marginal benefits of both ranked as : $18 (beanie) > $16 (beanie) > $15 (kewpie) > $14 (kewpie) = $14 (beanie). This satisfies the budget constraint also : 12x2 + 12x3 = 60.
