I need the answer as soon as possible

RR is considering a project which would cost $5,000 now. The annual benefits, for four years, would be a fixed income (ie not affected by inflation) of $2,500 a year, plus other savings of $500 a year in year 1, rising by 5% each year because of inflation. Running costs will be $1,000 in the first year, but would increase at 10% each year because of inflating labour costs. The general rate of inflation is expected to be 7472% and the organisation's required money rate of return is 16%. Is the project worthwhile? Ignore taxation
