2. Lauren likes the combination of Larry's Pizza and Dr. Pepper (soda) for dinner. When the price of a soda is $2 per unit and the price of a slice of pizza is $3, Lauren tries to maximize her satisfaction by consuming various units of soda and pizzas. The table below show you total utility of soda and pizza at different units.

Table 1. Total Utility (TU) and Marginal Utility (MU) of Pizza and Soda

Unit of Soda	TU (Soda)	MU (Soda)	Unit of Pizza	TU (Pizza)	MU (Pizza)
1	100	100	1	300	300
2	180	80	2	540	240
3	240	60	3	720	180
4	280	40	4	840	120
5	310	30	5	900	60
6	330	20	6	900	0

(1) Fill the two columns of marginal utility (MU) of soda and pizza.

(2) When Lauren maximizes her satisfaction with 4 sodas ($2 each), how many pizzas she should purchase at $3 each slide?

(3) If the price of pizza increases to $6 per slide, ceteris paribus, how may slides of pizzas should she purchase to maximize her total satisfaction?
