Jason was due to make loan payments of $250 today, $300 in two months, and $580 in four months. However, he has agreed instead to make a single equivalent payment $X one month from today. Determine the size of the single equivalent payment $X if the interest rate is 12% pa and the agreed focal date is one month from today (Month 1). Answer the following questions, and choose the closest answer from the possible choices following each question: If the focal date is one month from today, which variable does the payment $250 represent? (Choose from S, P, t, or r If the focal date is one month from today, which variable does the payment $300 represent? (Choose from S, P, t, or What value of "t" should you apply to the second loan payment of $300? (Express in 8 decimals) What periodic interest rate should you apply to the third loan payment of $580? (Express in 8 decimals) How many focal date equivalent values do you need to determine before solving for SX? Your answer for $X at the focal date is Choose... Choose Choose.. = Choose Choose (Carry all the decimals in the computation until completion, then round Choose... the final answer to two decimal places)
