I just want to make sure I got this problem right. TIA!

Compute the NPV statistic for Project Y if the appropriate cost of capital is 10 percent. (Negative amount should be indicated by a minus sign. Do not roun dintermediate calculations and round your final answer to 2 decimal places.)

Time: 0 1 2 3 4

Cash flow: -$8,600 $3,750 $4,580 $1,920 $700

My answer is NPV=$514.85. Is it right or wrong? Can you please show me how it's done if I got it wrong?
