Turtles can live a long time. This stem-and-leaf plot shows the ages (in years) of the turtles in the reptile house of the Kalamazoo Zoo. A box turtle and a map turtle escape from the reptile house of the Kalamazoo Zoo. The box turtle is older than the map turtle. The average age of the turtles remaining at the zoo after the escape is 1 year less than the average age before the escape. What is the age of the escaped box turtle?

The total age of the turtles is 440 and the average is 22. After 2 turtles escaped, there were 18 turtles left with an average of 21 so the total age is now 378. The sum of the ages of the two escaped turtles is 62 so one is 26 and the other is 36, so the age of the box tutle is 36.

:D
