How do you calculate part B? Is the formula listed correct?

Consider the following uneven cash flow stream: Year 0 Cash Flow $2,000 2,500 1 wn 1,500 3,000 4,500 a. What is the present (Year O) value of the cash flow steam if the opportunity cost rate is 10%? PV=P*(1-(1+r)^-N)/r PV= 2000+2000/(1+1)+1500/(1+. 1)^3+2500/(1+1)^4+4000/(1+. 1)^5 $9,136.37 b. What is the future (Year 5) value of the cash flow stream if the cash flows are invested in an account that pays 10% annually? FV=P*((1+r)^N-1)/r
