To show: It is impossible for three consecutive integers to have a sum that is 200 more than the smallest integer.

Answer to Problem 19P
The assumption is false
Explanation of Solution
Given information:
To show it is impossible for three consecutive integers to have a sum that is 200 more than the smallest integer.
Let the smallest integer be
Then the other two integers will be
Let us assume that it is true
According to the question,
Subtract
Subtract 200 from each side,
Divide each side by -2
s
which is not an integer, hence assumption is false

Each acre of oats requires 100 lbs of fertilizer and 1 hour of labor. Each acre of corn requires 50 lbs of fertilizer and 2 hours of labor. The farmer has 5000 lbs of fertilizer and 100 hours available for labor. If the profit is $60 from each acre of oats and $100 from each acre of corn, what planting combination will produce the greatest total profit? a) Fill in the following chart to help organize the information given in the problem: Oats Labor Fertilizer Land Profit b) Write down the question of interest.
