Question 223524: This is really hard for me :(
This Company manufactures three types of dweezle, type K, Type Z, and type F. Each type of dweezle is composed of two compounds, iron and zinc. Each pound of type K is 12 ounces of iron and 4 ounces of zinc while each pound of type Z is 12 ounces of zinc and 4 ounces of iron. Type F requires 8 ounces of each per pound.
Zinc is somewhat more difficult to work with, making type Z more costly to produce. A pound of type Z requires 9.6 man-hours to produce while a pound of type K requires only 6 man-hours and type F only 8.
The company has 125 pounds of zinc and 175 pounds of iron and only 2180 man-hours available for production, how many of type K and type Z can the Company make?
Goodness this is a pain, I tried and tried and keep getting different solutions. Please HELP!
