- Agriculture At a certain vineyard it is found that each grape vine produces about 10 lb of grapes in a season when about 700 vines are planted per acre. For each additional vine that is planted, the production of each vine decreases by about 1 percent. So, the number of pounds of grapes produced per acre is modeled by An=700+n10-0.01n where n is the number of additional vines planted. Find the number of vines that should be planted to maximize grape production.arrow_forwardA company sells $160,000 worth of printing paper during its first year. The sales manager has set a goal of increasing annual sales of printing paper by $20,000 each year for 9 years. Assuming that this goal is met, find the total sales of printing paper during the first 10 years this company is in operation.arrow_forwardThe number N of beavers in a given area after x years can be approximated by N=5.5100.23x,0x10.

- Paying Off a Credit Card Suppose you owe 15, 000 on a credit card that carries an APR of 24. Because the balance is so high, you choose to stop charging and pay off the card. You can afford to make only the minimum monthly payment, which is 5 of the balance. Then your balance after t months is given by B=15,000(1.020.95)tdollars. How many payments will you have to make to get the balance below 100?arrow_forwardAgriculture the number of apples produced by each tree in an apple orchard depends on how densely the trees are planted. If n trees planted on an acre of land, then each tree produce 900 - 9n apples, so the number of applesproduced per acre is A(n) = n(900 - 9n) How many trees should be planted per acre to obtain the maximum yield of apples?arrow_forwardFinance A family has a monthly mortgage payment of $760, which is 16 of their monthly income.
