4. (21 points) Being able to determine what equation best models a scenario is an important skill. You will practice this in here. On the final exam, you will both need to determine which equation to use and then use it to answer the question. For each question, 1. state what type of model applies to the problem (lump-sum savings, future value annuity, present value annuity, or loan) 2. write the formula you would use and 3. circle the variable that you would solve for. Solving the problems is not needed (or graded). An example is done for you. Also, a list of formulas is provided on the next page. The same information will be made available to you in the exam. Problem Type Equation with Variable Circled a) A lottery prize worth $6,000,000 is awarded in pay- ments of $25,000 monthly (end of the month) for 20 years. If the money is in an account earning 4% in- terest compounded monthly, what is the real value of the lottery prize before payments start? Present Value Annuity b) Jax has an online business that earns him $8000 per year, which he deposits, at the end of each year, in an
