Math Formula Functions question help

Question

For a manufacturing company with w workers working h hours per day and producing a total of I items, labor productivity P=P(w,h,l) is measured by the function

(P=I/wh) Items per worker hour

Suppose a company produces 800 items per day and each worker works 6 hours per day. The company budget allows for no more than 15 workers. What is the labor productivity if there are 12 workers?

_______items per worker hour. (Round to the nearest thousandth)

Ive been having so much trouble with this question and I just dont know what to do. Its really frustrating me and Im sure its something so simple that I didnt see at first. Please if anyone knows how to solve this, I'd really appreciate the help

Answer 1

P = # items / # of worker-hours

= 800 items / 12 workers * 6 hours

= 11.111 items per worker-hour
