Your bagel store needs to order cream cheese from three different suppliers since one cannot fill all of your needs. You order from Cheesy Cream Corp. (CCC), Super Smooth & Sons (SSS), and Bagel's Best Friend Co. (BBF). This month, you need to order 110 tons of cream cheese. The cost per ton for each supplier is $70 (CCC); $55 (SSS); $60 (BBF). Your total monthly budget is $6,575. You will be purchasing one-third the amount of cream cheese purchased from SSS from CCC. How much cream cheese should you order from each supplier?

Project #3 Problem#1 Analyze the circuit given in Figure #1. Use MatLab to obtain the following plots: Vs(t) = 100 cos(t) R1 400 Vi(t) v1(t) vs. t V2(t) vs. t R2 600 i(t) V2(t) vs(t) vs. t Verify KVL, that is: v1(t) + V2(t) = vs(t) i(t) vs t Figure#1 Pr? (t) vs. t Pr2 (t) vs. t Pvs (t) vs. t Verify (conservation of energy) that is: Pr2 (t) + Pr? (t) = Pvs (t) All plots over 2 periods \(T = \frac{2\pi}{\omega}, \omega = 1\) Problem#2 Verify the max. power transfer theorem by replacing R2 by the following Matlab relation (/vector) R2 = 10: 5: 600. Then obtain plots of: PR2 vs. R2 IR2-RMS vs. R2 VR2-RMS vs. R2
1. Boudica and Arthur are both Homo economicus engaging in exchange. Their utility functions are given by Equations 1 and 2: $\qquad u^B = \frac{1}{2} \ln x^B + \frac{1}{2} \ln y^B$ (1) $\qquad u^A = \frac{1}{2} \ln x^A + \frac{1}{2} \ln y^A$ (2) They are working out an exchange of archers ($x$) and knights ($y$) for the defense of their respective realms. Boudica currently has 40 archers and 40 knights. Arthur has 20 archers and 60 knights. True or False & Explain: Boudica and Arthur's initial allocations (endowments) are not Pareto efficient. 2. Use the same endowments and utility functions (Equations 1 and 2) as you did for the previous short question about Arthur and Boudica. Boudica — because of her legend as a powerful warrior-queen — has take-it-or-leave-it power over Arthur (who, although also legendary, made the fatal error of leaving his sword stuck in a stone). True or False & Explain: Boudica will offer (in round numbers and approximately) 7 archers in exchange for 15 knights leaving Arthur with a post-exchange Pareto-efficient allo- ciation of 27 Archers and 45 knights. 3. True or False & Explain: In exchange with price-setting power, when a player's incen- ive compatibility constraint is satisfied, then the player's participation constraint is automatically satisfied, and when a player's participation constraint is satisfied, then the player's incentive compatibility constraint is automatically satisfied.
