I'm getting tired of these questions! urrrrggghh. High school needs a better system for students to have questions answered... sorry guys for repeatedly posting questions on here today.
24. Stan needs to move some excess topsoil from his farm. He can hire a dump
truck and a driver for $60/h. The driver will take 30 min to deliver a load of
topsoil and return to the farm. One person will take 40 h to load the truck
with soil. Labourers get $18/h (whether they are loading the truck with soil
or waiting for the truck to return). How many labourers should Stan hire to
minimize the cost per load? What is the minimum cost?
I'm supposedly waayyyy off. Answer should be 5.
