1. Chad has an income of I = $100, which he dedicates to purchasing soda and pizza. The price of soda is $1 per can, while that of pizza is $2 per slice. 1.1 Find the equation of his budget constraint and represent it graphically. 1.2 How does Chad's budget constraint change when his income increases to $150? 1.3 Consider now that Chad's university subsidizes pizza, decreasing its price by $1 per slice. His income is $150, and the price of soda is $1 per can. Demonstrate Chad's new budget constraint.
