Assume that product Alpha and product Beta are both priced at $1 per unit and that Ellie has $20 to spend on Alpha and Beta. She buys 8 units of Alpha and 12 units of Beta. The marginal utilities of the last unit of Alpha and Beta that she purchases are 40 utils and 20 utils, respectively. This indicates that:
a) Ellie should make no change in consumption. given another dollar,
b) Ellie should buy an additional unit of Beta. in order to maximize utility,
c) Ellie should buy more Beta and less Alpha. in order to maximize utility,
d) Ellie should buy more Alpha and less Beta.

Arival company manufactures fuel tanks for cars using a different production technique. the total weekly cost (in dollars) of producing x tanks is given by c(x) = 10000 +90x - 0.04x2 find the marginal cost at a production level of 500 fuel tanks per week to approximate the cost of the 501st unit (round to the nearest 2 decimal places, if needed)
