Kathy puts $3000 into an account that pays 5% simple interest annually. a) Create a linear model to relate the amount of the investment, A, to time, t, in years. b) Graph the amount of the investment versus time. c) How long will it take for Kathy’s investment to double in value? d) What interest rate is required for the investment to double in value in 10 years?

You invest $10,000 into an account that earns 4.5% interest each year. Give the equation of the line and give the total amount you would have after 30 years.

When the rose attendance related to the linearly What price dropped to $, the average the attendance is tinca price. to 28000. Assume ticket ticket would the price would maximize revenue $-

look at image below and answer: a) From the table, determine if the data represents a linear, quadratic or exponential relationship.  Justify your answer. b) Joe’s grandfather’s 65 year old friend drives a Porsche.  His insurance rate is only $500.35 per year.  Does this information fit the model you chose above? Explain. c) Graph the data (remember to include Joe’s grandfather’s friend’s insurance rate).  Determine the equation of best fit. d) Use your results to determine Joe’s annual insurance rate when he purchases his Porsche, by making an eqaution and then sketching the graph   e) If Joe decides to pay his insurance monthly instead of yearly, what will be his total monthly costs for his car payments and insurance?  Should Joe rethink his Porsche dream?  Explain your thinking.
