Please solve it clearly and explain all the steps

A shale oil production project will cost $300,000 upfront but generate $?0.000 at the end of each year for the rst 4 years. and $30,000 at the end of each year in the following 3 years. No value will remain after that. Calculate the net present value of the project at 5% annual opportunity cost of capital. 0 less than -$20 0 at least $20. but less than -$10 0 at least $10. but less than 50 O at least 50. but less than $10 Q at least $10. but less than 520 O at least $20 Question 7 Q (Continued from the last question.) Calculate the internal rate of return of the above project. (Ignore 5% opportunity cost of capital in the last question.) 0 less than 4.5% Q at least 4.5%, but less than 5% O at least 5%. but less than 6%
