Imagine a project that begins in year 0 and continues through year 4. In years 1-4 it generates extra sales of 120, 150,170 and 210; a reduction in labor expense of 20 per year and an increase of raw materials expense of 50 per year. Capex in year 0 is 100, which is depreciated to 0 using straight line over years 1-4. Compute annual EBIT and aggregate it (add up without any time value of money adjustments) over years 0-4. What is that value?

A) 330
