I need help with the following question. Thank you!

Use the information below to answer questions 3 through 6. An oligopolistic industry consists of only two rms, Angel & Co. and Barton Inc. The two rms agree to collude on a level of output at 20 units per rm, which leads to a market price of $25. After one year of colluding, Angel 8. Co. begins cheating by increasing output to 30 units. Barton Inc. continues to produce 20 units as agreed. The market price falls to $20. Assume that it costs each rm $5 to produce each unit. What is the total prot in the industry during the year of mutual collusion? Answer here
