Mateo and Kristen want to know the combined number of arcade games they played today. They both played 4 games for a dollar, but Mateo also won 5 free games. Kristen says the combined number is 4M + 5 + 4K, where M is the combined amount is5(M + K) + 4. Who is right? Why?
Im pretty sure Kristen is right because Kristen didn't win free games. 4M is for each game Mateo has played while 4K is for each game Kristen played in a sense of paying. The 5 is standalone for the free since it's a constant.
