A baby that weighs 7 1b at birth may increase his weight by 11% per month. Use the Functionf(r) =K(1 +r)t, where K is the initial value, r is the decimal value of the percentage of increase (r=0.11) and is the time in months. How much would the baby weigh in one month? Two months? Six months? Nine months? One year? Round your answers to the nearest tenth of a pound. Age Weight (Ibs) ht X o one month two months six months nine months ' one year The cost y (in dollars) of a collect call x minutes in length can be described by the equation y = 0.88x. Use this equation to complete the table of values. X % 9 15 L 10 || L] L] The taxes on a house assessed at $78,000 are $3510 a year. If the assessment is raised to $113,000 and the tax rate did not change, how much would the taxes be now? The taxes on the house with an assessment of $113,000 are S| ' X O The Chinese government has been accused of manipulating the value of its currency, keeping it artificially low in order to give the country an export advantage. Some economists feel that the yuan is valued at 20% less than it should be compared to the U.S. dollar. At the exchange rate of one yuan = 0.185 dollar, a $22,000 car would cost approximately 118,919 in yuan. If the exchange rate was adjusted, the equation y =4.3d can be used to convert dollars to yuan. How much would that affect the price of that car in China? Rounding to the nearest yuan, the car would cost | | yuan less if the exchange rate were adjusted. 5 s Use a variation model to solve for the unknown value. The number of turkeys needed for a banquet is directly proportional to the number of guests that must be fed. Master Chef Rico knows that he needs to cook 7 turkeys to feed 91 guests. Note: Round up the answer to the nearest whole number, if necessary. Part 1 of 4 (a) How many turkeys should he cook to feed 117 guests? The chef should cook ' ' turkeys for 117 guests. % 5 Part 2 of 4 (b) How many turkeys should he cook to feed 143 guests? The chef should cook ' ' turkeys for 143 guests.

If b = 6 when c = 3, find b when c is 2. b = X 5A survey was conducted when the world population was about 7 billion, and 2.03 billion people wanted to stay in their country. Among those in the survey that said they wanted to leave their current country, 24 out of 71 said they'd like to move to the United States. The two next-highest proportions were for Canada and Great Britain, each at 7 of 71. How many of the people who want to move would choose the United States? Round to the nearest hundredth. Of the 4.97 billion people who want to move, ' ' billion people want to move to the United States. The percentage of the adult population that smokes can be modeled by the function P(x) whose graph is shown below. The input x is years after 1955. o Use the percentage of adults that smoke in 1955 and 2005 to find a linear formula for the function P(r) P(x) = |:' g
