Java DBC           1.0         4.5     3.0     3.0     7.5

Total 
 (man-weeks)       8.5        27.0    23.0    16.5    74.0

Rate 
 ($/man-weeks)    $200        $450    $400    $300

Cost            $1,700     $12,150  $9,200  $4,950 $28,000    


Step 3. Avg. Cost (estimated cost) = (31,740 + 28,000) / 2 = $29,870
