Hello, this is a study guide for an upcoming exam. I need help with understanding how the teacher got the answer in STEP BY STEP format please! Thank you for the help. (step by step will help me practice problems with different numbers).

The answers are in red: I need step by step help to find the provided solutions.

Number 1: A, B, C, D

PROBLEMS Show all your work. If you get stuck on graphs or calculations, be sure to write out your reasoning for how to answer the question. Credit depends on showing all your work and reasoning. (5 points for each sub- question unless otherwise noted; TOTAL POINTS THIS SECTION = 43) 1. Consider Coumot duopolists facing demand P=50-Q. Both rms\" total costs are equal to 1543. A. Find the equilibrium output levels for both rms. q1=q2=35f3 = 11.67 For aiiprobiems, just writing down the answer without it being clear where it comes from does not receive credit. E. Find price and prots for the two rms in equilibrium. P=80f3 = 26.6? Prot 1 = Prot 2 =1225i9 = 136.11 C. Firm 1 has the opportunity to switch to a different production technology that would reduce its total costs to 10:91 (Firm 2 '3 costs do not change). The two rms are still in Coumot competition. What are the output levels in the new equilibrium? {11:15 , (12:10 D. Find price and prots for the two firms in Cournot competition. Should Firm 1 switch technology? P=25, Prot 1 = 225, Prot 2 = 100 Firm 1 should switch because Prot 1B
