 Question 257360: #1)Research for a given orchard has shown that, if 100 pear trees are planted,then the annual revenue is \$90 per tree. If more trees are planted they have less room to grow and generate fewer pears per tree. As a result, the annual revenue per tree is by \$0.70 for each additional tree planted. No matter how many trees are planted, the cost of maintaining each tree is \$7.40 per year. How many pear trees should be planted to maximize the profit from the Orchard for 1 year? #2) The sum of two numbe is 30 and their product is a maximum. Find the two numbers.
