- A universal life policy is issued to a life aged 45. Death benefit is 10,000 and the policyholder pays an annual premium of 200 at the beginning of each year. Expense charges are 30% of first year premium and 5% of renewal premiums. Interest credited is 6% per year and interest assumed in the cost of insurance is 4% per year. Cost of insurance is based on Makeham's mortality, H = 0.01+0.0001(1.05*). The account value at the beginning of the 7th year, before any premium is paid, is 1,500. Calculate, to the nearest integer, the account value at the end of the 7th year.arrow_forwardConsider a savings account with an interest rate of a = 0.1 and an initial investment of y(0) $100. At t=5, a one-time deposit of $50 is made. At t = 10, a one-time withdrawal of $40 is made. Set up and solve an initial value problem for the dollar value y(t) of the account. Sketch the graph of the solution. 1arrow_forwardThe scrap value of a machine at the end of its useful life is given by S(n) = C(1-r)", where C is the original cost, n is the useful life of the machine in years, and r is the constant annual percentage of value lost. Find the scrap value of the following machine. Original cost, $49,000; life, 11 years; annual rate of value lost, 13% S=$ (Round to the nearest cent.)arrow_forward

This makes the determination of your monthly payment on a loan more complicated than you might expect. If you borrow P dollars at a monthly interest rate of r (as a decimal) and wish to pay off the note in t months, then your monthly payment M = M(P,r,t) in dollars can be calculated using the following function. M = Pr (1+r)t (1 + r)² - 1 The above function can be rearranged to show the amount of money P = P(M, r, t) as shown below, in dollars, that you can afford to borrow at a monthly interest rate of r (as a decimal) if you are able to make t monthly payments of M dollars. 1 - - - - - (1 - 1 + ²) 1 (1 r) P=Mx Suppose you can afford to pay $300 per month for 3 years.

- The stock market investment is loosing its value. The equation is given by ( 4 ) th where P is the principal (the initial value of investment), in dollars, and A A(t) = P 9 is the ammount of investment, in dollars, after t days. If the principal was $200, at what rate, to nearest tenth of a dollars per day, is the investmant deacreasing at 2 days? A) -25.3 $/day B) -26 $/day C) 26 $/day D) 25.3 $/dayarrow_forwardYou are having a dinner catered. You pay a rental fee of $110 for the dining hall, and you pay the caterer $10 for each person who attends the dinner. (a) Suppose you just want to break even. (i) How much should you charge per ticket if you expect 50 people to attend? (Round your answer to the nearest cent.) (ii) Use a formula to express the amount you should charge per ticket as a function of the number of people attending. (Let a be the number of people attending and C the amount in dollars you should charge per person.) (iii) You expect 65 people to attend the dinner. Use your answer to part (ii) to express in functional notation the amount you should charge per ticket, and then calculate that amount. (Round your answer to the nearest cent.) ) = $ per ticket (b) Suppose now that you want to make a profit of $100 from the dinner.
