Question 204841: Jack and Bob are farmers. Jack grows apples, Bob grows oranges. On May 9th, Jack has harvested 5000 apples, and Bob has harvested 300 oranges. However, Jack will harvest apples at a rate of 5/hr, and Bob will harvest oranges at a rate of 30/’hr. If Jack and Bob eventually end up with the exact same number of fruits, Jack agreed to eat 100 apples, and both will stop harvesting. If Jack and Bob never end up with the exact same number of fruits, both will stop harvesting on the hour that Bob has more fruit than Jack.
What is the mathematical equation used to solve this problem?
Will Jack have to eat 100 apples?
How many apples does Jack have at the end? How many oranges does Bob have at the end?
If two painters can paint a house in 5 hours, how many painters does it take to paint twenty houses in 10 hours. All painters paint at effectively the same speed.

You can put this solution on YOUR website! part B)
Since it takes 2 painters 5 hrs to paint 1 house, it would take the same 2 painters 100 hrs to paint 20 houses or 200 hrs for one painter.
So by dividing 200 by 10 (the aloted time) it would take 20 painters 10 hrs to paint 20 houses.
