Mika earns $379 per week which she spends entirely at the grocery store, purchasing either food or alcohol. The price of food is $1/unit, while the price of alcohol is $4/unit. Mika receives an additional $50/week in food stamps that can only be only be used to buy food at the grocery store (so, this money could be used to buy food but NOT alcohol). Mika knows someone who will give her cash in exchange these food stamps at a rate of $0.50 in cash for every $1 in food. stamps. Cash, of course, can be used to buy either food or alcohol. What is the vertical coordinate of the vertical intercept of Mika's budget constraint if she were to graph quantity of food on the horizontal axis and quantity of alcohol on the vertical axis? (Note: The answer may not be a whole number, so round to the nearest hundredth)
Joanne has just completed high school and is trying to determine whether to go to junior college for two years or go directly to work. Her objective is to maximize the savings she will have in the bank five years from now.
If she goes directly to work, she will earn $22,000 per year for each of the next five years. If she goes to junior college, for each of the next two years she will earn nothing—indeed, she will have to borrow $6,000 each year to cover tuition and books. This loan must be repaid in full three years after graduation. If she graduates from junior college, in each of the subsequent three years, her wages will be $41,000 per year. Joanne’s total living expenses and taxes, excluding tuition and books, equal $15,000 per year.

- Stan Moneymaker needs 15 gallons of gasoline to top off his automobile’s gas tank. If he drives an extra eight miles (round trip) to a gas station on the outskirts of town, Stan can save $0.10 per gallon on the price of gasoline. Suppose gasoline costs $3.90 per gallon and Stan’s car gets 25 mpg for in-town driving. Should Stan make the trip to get less expensive gasoline? Each mile that Stan drives creates one pound of carbon dioxide. Each pound of CO2 has a cost impact of $0.02 on the environment. What other factors (cost and otherwise) should Stan consider in his decision making?arrow_forwardIn the quaint village of Chromaville, all of the residents (including their mayor) are colorblind.

- From California to New York, legislative bodies across the United States are considering eliminating or reducing the surcharges that banks impose on noncustomers, who make $14 million in withdrawals from other banks’ ATM machines. On average, noncustomers earn a wage of $22 per hour and pay ATM fees of $2.75 per transaction. It is estimated that banks would be willing to maintain services for 6 million transactions at $1.25 per transaction, while noncustomers would attempt to conduct 18 million transactions at that price. Estimates suggest that, for every 1 million gap between the desired and available transactions, a typical consumer will have to spend an extra minute traveling to another machine to withdraw cash.Based on this information, what would be the nonpecuniary cost of legislation that would place a $1.25 cap on the fees banks can charge for noncustomer transactions?Instructions: Enter your responses rounded to the nearest penny (two decimal places).arrow_forwardFrom California to New York, legislative bodies across the United States are considering eliminating or reducing the surcharges that banks impose on noncustomers, who make $12 million in withdrawals from other banks' ATM machines.
