According to one mathematical model, the average life expenctancy for American men born in 1900 was 55 years. Life expectancy has increased by about 0.2 year for each birth year after 1900. If this trend continues, for which birth year will the average life expentancy be 71 years? a) Write an equation to model the problem. Let t represent the number of years after 1900. For example, t = 12 would represent the year 1912. b) Solve the equation, then answer the question given above. You are asked for a year, not a value for t.

Question 10 (10 points) 4) Listen You purchased property 10 years ago for $15,000. Today that same property has a value of $27,000. What is the percentage change in the value of the properY?

5. Assume food prices have risen about 4% per year for the last five years. a. If a gallon of milk cost $2 five years ago, what does it cost today? b. If a gallon of milk cost Sx five years ago, write an expression for its cost today. c. If a gallon of milk costs $3.50 now, what did it cost five years ago? Write and solve an equation to answer the question. Let x cost of a gallon of milk five years ago d. Ifmilk prices increase 4% per year for five years, what is the overall percent ncrease

Part 1) According to one mathematical model, the average life expenctancy for American men born in 1900 was 55 years. Life expectancy has increased by about 0.2 year for each birth year after 1900. If this trend continues, for which birth year will the average life expentancy be 75 years? a) Write an equation to model the problem. Let t represent the number of years after 1900. For example, t = 12 would represent the year 1912. Answer:   b) Solve the equation, then answer the question given above. (Note: You are asked for a year, not a value for t.)   Part 2) Wilma drove at an average speed of 50 mi/h from her home in City A to visit her sister in City B. She stayed in City B 25 hours, and on the trip back averaged 35 mi/h. She returned home 48 hours after leaving. How many miles is City A from City B
