2. Suppose you decide to start your own business. You quit a job at which you earned $38,000 per year and invest $20,000 of your own money (which had been earning 10% in a mutual fund). You incur raw materials costs of $23,000. After 1 year you earn revenues of $23,000 at your new business. You decide to go back to your old job, and you sell your business for $20,000. A friend tells you "Hey, you broke even-- you got your money back when you sold the business." So, what do you think? What is the profit on your 1-year business venture? (Assume no other input costs, and be sure to count the sale of your business as income.)
Answer 1:
# of units | MUX | MUX/$2 | MUY | MUY/$3 | MUY/$4.5 |
1 | 10 | 5 | 5 | 5/3=1.67 | 5/4.5=1.11 |
2 | 8 | 4 | 4 | 4/3=1.33 | 4/4.5=0.89 |
3 | 4 | 2 | 3 | 3/3=1 | 3/4.5=0.67 |
4 | 2 | 1 | 2 | 2/3=0.67 | 2/4.5=0.44 |
5 | 1 | 0.5 | 1 | 1/3=0.33 | 1/4.5=0.22 |
a.
At income=$17, Bill will consume both goods at a level where MUX/PX=MUY/PY.
If Bill consumes 4 unit of X and 3 unit of Y it will get maximum utility.
b.
If price of Y increased to $4.5 then Bill will consume 4 units of X and only 2 units of Y (now he cannot afford 3 units of Y and X is giving it more marginal utility than Y) at income of $17.
Answer 2:
Cost of starting business(including opportunity cost)=$38,000+$20,000+$2,000(earnings from mutual fund 10% of 20,000)+$23000(raw material costs=$83,000.
Revenues during business=$23000 and sale price of business=$20000.Total income=$43,000.
At break even cost should be equal to income, so profit should be $40,000 ($83,000-$43000) to break even.
