Given, Lorena is comparing the winning percentages of two baseball teams. The Scorpions have won 20 out of 35 games. The Iguanas have won 10 out of 34 games. There are x games remaining until the playoffs. In the remaining events, Scorpions wins 0 games and Iguanas win y and reach the same winning percentage as the Scorpions. Now, total games played by Scorpians is 35+x. Number of games they win is 20 out of(35+x). Then, the percentage of winning=35+x20×100 total games played by Iguanas is 34+x. Number of games they win is34+x10+y. Then, the percentage of winning=34+x10+y×100 At the end, both winning percentage is same. Therefore,35+x20×100=34+x10+y×10035+x20=34+x10+y Thus, fourth option i.e., 34+x10+y=35+x20 is the right option.
