You are given the following accumulation function information:

a(1)=1.2 a(2)=1.5 a(3)=2.0 a(4)=3.0

1.) the value at time t =2 is 300. Determine the accumulated valueat time t = 3

2.) Determine thediscounted value at time t=1 of a value of 600 at time t=4

3. Given 480 at time t=1, plus 300 at time t=3:

a. determine the total presnt value at time t=0 of the two payments

b. determine the total accumulated value at time t =4 of the payments

c. determine the total value at time t=2 of the payments

4.) determine the amount of interest earned from time t=2 to time t=4 if 500 is invested at time t=0

5.) determine the amoint of interest earned from time t=2 to time t=3 is 300 is invested at time t=0

6.) determine the amount of interest earned fromtime t=2 to time t=4 if 240 is invested at time t=1 and an additional 300 is invested at time t=3.
