Answer subpart 4,5,6 only.

Question 7:
Logan has preferences over olives (x₁) and ice creams (x₂). He prefers to eat them separately but
not together, which is represented by:
U(x₁, x₂) = x² + x².
Also suppose his income is $200 and the prices of olives and ice creames are px₁ = $1 and
Px₂ = $2, respectively.
1. Is this convex preferences or concave preferences?
2. Solve for the bundle that satisfis the tangency condition.
3. What's the level of utility using the bundle you just solved in Q7.2?
4. Consider spending all of your income on olives (x₁). What's the utility from this bundle?
5. Which bundle does Logan prefer between the bundle in Q7.2 and Q7.4? Does the tangency
condition lead to the optimal bundle?
6. What's the optimal bundle when price of olives is $3.
