In Exercises 15-42, translate each argument into symbolic form. Then determine whether the argument is valid or invalid. You may use a truth table or, if applicable, compare the argument’s symbolic form to a standard valid or invalid form. (You can ignore differences in past, present, and future tense.) If it rains or snows, then I read. Iam reading . ∴ It is raining or snowing .

4. Let A = {a, b, c, d, e, f}, B = {e, f, g, h} and C = {a, e, h,i}. Let U = {a, b, c, d, e, f, g, h, i, j, k}.
• Draw a Venn Diagram to describe the relationships between these sets
Find (AB) NC
• Find (AC) UB
Find AUBUC
• Find (BC) N (A - C)
7. A consumer lives on an island where she produces two goods x and y according to the
production possibility frontier x² + y² < 200 and she consumes all the goods. Her utility function
is U(x, y) = x y³. She faces an environmental constraint on her total output of both goods. The
environmental constraint is given by x + y ≤20.
•
(a) Write down the consumer's optimization problem.
(b) Write out the Kuhn-Tucker first order conditions.
(c) Find the consumer's optimal consumption bundle (x*, y*).
3. Answer the following questions:
(a) Given the marginal propensity to import M'(Y) = 0.1 and the information that M = 20
when Y = 0, find the import function M(Y).
(b) Given a continuous income stream at the constant rate of $1,000 per year, what will be the
present value II if the income stream terminates after exactly 3 years and the discount rate is 0.04?
(c) What is the present value of a perpetual cash flow of $2,460 per year, discounted at r = 8%?
