Dave fletcher was able to determine the activity times for construction his laser scanning machine. fletcher would like to determine es, ef, ls, lf, and slack for each activity. the total project completion time and the critical path should also be determined. here are the activity.

activity time(weeks) immediate predecessor(s) activity time(weeks) immediate predecessor(s)

a 5 - e 3 b
b 8 - e 7 b
c 2 a g 10 c, e
d 3 a h 8 d, f

Arival company manufactures fuel tanks for cars using a different production technique. the total weekly cost (in dollars) of producing x tanks is given by c(x) = 10000 +90x - 0.04x2 find the marginal cost at a production level of 500 fuel tanks per week to approximate the cost of the 501st unit (round to the nearest 2 decimal places, if needed)
