d. Suppose the demand function for good X is given by: Qdx = 15 - 0.5Px - 0.8Py where Qdx is the quantity demanded of good X, Px is the price of good X, and Py is the price of good Y, which is related to good X. i. if the price of good Y is $10 and the price of good X decreases from $5 to $3, what is the price elasticity of demand for good X? Is the demand elastic, unitary elastic, or inelastic? ii.

h. If we increase the side length of the square from 1.9 cm to 4.4 cm, the square's perimeter increases from 7.6 cm to 17.6 cm. i. Determine the value of ΔP as s increases from 1.9 cm to 4.4 cm. ΔP = 10 j. As the values s and P vary together in the relationship where P = 4s, define ΔP in terms of Δs. ΔP = 4Δs k. Which of the following describes a relationship defined by the formula P = 4s? (Select all that apply.) Since s and P are proportional, P varies at a constant rate of change with respect to s. For any change in s, Δs, away from a point (s₁, P₁) in the relationship, ΔP = 4Δs. Given any point (s, P) in the relationship, P is always 4 times as large as s. Given any two points in the relationship (s₁, P₁) and (s₂, P₂), (P₂ - P₁) / (s₂ - s₁) = 4. The point (4.4, 17.6) in the relationship conveys that 17.6 = 4(4.4).
