please answer this for me. equation of value example 10, 11,12

EXAMPLE 10 I set up and solve an equation of value: 1 Draw a time diagram with all the dated values 2. Select the focal date. 3. Pull all the dated values to the focal date using the stated interest rate 4. Set up the equation of value and then solve. A debt of RM 300.00 due in four months and another of RM 1,000.00 due in nine months are to be settled by a single payment at the end of six months. Find the size of this payment using the present as the focal date, assuming money is worth 6% per annum simple interest 17 EXAMPLE 12 EXAMPLE 11 Debts of RM 500.00 due 20 days ago and RM 400.00 due in 50 days are to be settied by a payment of RM 600.00 now and a final payment 90 days from now. Determine the value of the final payment at a simple interest rate of 11% with a focal date at the present A person borrows RM 1,000.00 at 6% simple interest.
