Imagine that Steven told Deana that if she married him, he would support the baby even if they got divorced. As soon as they are engaged, Deana has her assistant email an agreement to Steven that states "I make this solemn promise in consideration of marriage. In the event that Deana and I get divorced I promise to pay $500 per month in child support for three years or until the child’s 18th birthday, whichever comes first." Steven reviews the agreement and adds his e-signature at the bottom and sends it back to Deana.

a. Will this written promise be enforceable:

1. No, because Steven did not sign it by hand.
2. No, because it is too short.
3. No, because Deana did not provide consideration.
4. Yes, because it is signed and reasonably certain.

b. Does Deana need to sign the agreement in order for it to be enforceable

a. No, because she is the party seeking to enforce the agreement
b. Yes, the agreement must be signed by both parties
c. The agreement will not be enforceable because Steven's e-signature is invalid

5. profit maximization and shutting down in the short run suppose that the market for polos is a competitive market. the following graph shows the daily cost curves of a firm operating in this market. 0 2 4 6 8 10 12 14 16 18 20 50 45 40 35 30 25 20 15 10 5 0 price (dollars per polo) quantity (thousands of polos) mc atc avc for each price in the following table, calculate the firm's optimal quantity of units to produce, and determine the profit or loss if it produces at that quantity, using the data from the previous graph to identify its total variable cost. assume that if the firm is indifferent between producing and shutting down, it will produce. (hint: you can select the purple points [diamond symbols] on the previous graph to see precise information on average variable cost.) price quantity total revenue fixed cost variable cost profit (dollars per polo) (polos) (dollars) (dollars) (dollars) (dollars) 12.50 135,000 27.50 135,000 45.00 135,000 if the firm shuts down, it must incur its fixed costs (fc) in the short run. in this case, the firm's fixed cost is $135,000 per day. in other words, if it shuts down, the firm would suffer losses of $135,000 per day until its fixed costs end (such as the expiration of a building lease). this firm's shutdown price—that is, the price below which it is optimal for the firm to shut down—is per polo.

Two assets have the following expected returns and standard deviations when the risk-free rate is 5%: asset a e(ra) = 18.5% σa = 20% asset b e(rb) = 15% σb = 27% an investor with a risk aversion of a = 3 would find that on a risk-return basis. a. only asset a is acceptable b. only asset b is acceptable c. neither asset a nor asset b is acceptable d. both asset a and asset b are acceptable

There is a small, family-owned store that sells food and household goods in a small town. the owners have good relations with the community, especially with local farmers who supply much of the food. the farmers aren't organized into a cooperative or union, and the store deals with each individually. suppose the store wanted to buy some farms to control the supply of certain vegetables. how would you classify this strategic move? select one: a. horizontal integration b. forward integration c. backward integration d. concentric integration
