In computing the equivalent present worth of each given cash flow series at period zero, which of the following expressions is incorrect? (a) P= $500(P/A, i, 4)(P/F, i, 4). (b) P = $500(F/A, i, 4)(P/F, i, 7). (c) P = $500(P/A, i, 7) – $100(P/A, i, 3). (d) P= $500[(P/F, i, 4) + (P/F, i, 5) + (P/F, i, 6) + (P/F, i, 7)].

How long will it take money to double if it is invested at (A) 11% compounded continuously? (B) 13% compounded continuously? (A) At 11% compounded continuously, the investment doubles in years. (Round to one decimal place as needed.) (B) At 13% compounded continuously, the investment doubles in years. (Round to one decimal place as needed.)

3B. The following equation describes the conversion of a cash flow into an equivalent equal payment series with N=10: A= [800+20(A/G,6%,7)] * (P/A, 6%, 7) (A/P,6%,7) + [300(F/A, 6%, 3)-500] * (A/F, 6%, 10) Reconstruct the original cash flow diagram.

Gurpreet already had a balance of $1700 on her credit card when she used it to purchase items worth another $335. The minimum monthly payment is 3% of the outstanding balance or $30 dollars, whichever is greater, and the interest rate is 19.7%, compounded daily. If Gurpreet pays only the minimum each month, how long will it take her to pay off the balance? How much interest would she end up paying?

Solve for the value of X in the Figure below so that cash flow A is equivalent to cash tlow B (i = 12% per year). $5,000 $2,000 Cash flow A 3X Cash flow B 2x
