Question

Ventaz corp manufactures small windows for back yard sheds.​ historically, its demand has ranged from 30 to 50 windows per day with an average of 42. alex is the one production worker and he works eight hours a​ day, five days a week. each order is one window and each window takes 5 minutes. alex plans to add doors to its product line and anticipates that they will average 4 doors per day. each door takes 540 minutes to install. what is the average waiting​ time, in​ minutes, if alex continues to be the only​ worker?

Answer 1

308 minutes

Step-by-step explanation:

The average waiting time =
`(42*5^2+4(540)^2)/(2*(480-(42*5)-540*4)))`

=
`(42*25+1166400)/(2*(480-(210)-2160)))`

=
`(1167450)/(-3780)`

= - 308.85 minutes

Thus; alex average waiting​ time, in​ minutes, 308 minutes if he still wants to continues to be the only​ worker.
