Problem 1. Use the cash flow diagram below to calculate the amount of money in year 5 that is equivalent to all the cash flows shown, if the interest rate is 10% per year 01 2 3 4 5 6 7 8 9 10 12 13 Year S1000 $2000 Problem 2. Determine the value in year 8 that is equivalent to the cash flows below. Use an interest rate of 10% per year. Year $1500 $2500 $2500 Problem 3 Find the value of x in the diagram below that will make the equivalent present worth ofthe cash flow equal to $15,000, if the interest rate is 10% per year P-$15,00 0 23 5 6 Year 1000 2000 Problem 4. The maintenance cost for a certain machine is $1000 per year for the first S years and S2000 per year for the next 5 years. At an interest rate of 12% per year, the annual worth in years I through 10 of the maintenance cost is closest to Problem 5. If a person begins saving money by depositing $1000 now and thern increases the deposit by $500 each year through year 10, the amou that wil be in the account in year 10 at an interest rate of 12% per year is closest to
