Population: Since birth rates are going down and people are living longer, the percent of the population that is 65 years old or older continues to rise. The percent of the U.S. population P that is at least 65 years old can be approximated by the equation P = 3.79(1.013), where trepresents the number of years since 1900. (a) What percent of the population will be 65 years of age or older in the year 1999? Round the answer to 2 decimal places. Number % (b) Predict the year in which people ages 65 or older will represent 26% of the population if this trend continues. Number

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.
