4. Lawn Mowing Chore
At my house, summer vacation means added chores for my three sons.
Saturdays the lawn must be mowed. Mark starts the mower and completes
1/3 of the lawn. Sam takes over and mows exactly 1/4 of the grass.
Josh then finishes off the last 700 square feet of the yard.
4A. What is the area of my yard?
4B. Bonus: The boys devised the plan for dividing the work and consider
it to be fair based on their ages. My youngest son is nine. Can you match
the names and ages of my three sons? Don't forget to explain how you found
your answer and let me know if you think that this is fair.
