Freddie and Jason have just opened the Texas Toothpick, a chain-saw sharpening and repair service located on Elm Street. The Texas Toothpick promises same-week repair service. Freddie and Jason are concerned that a projected dramatic increase in demand as the end of October nears will cause service to deteriorate. Freddie and Jason have had difficulty attracting employees, so they are the only workers available to complete the work.
Safety considerations require that they each work no more than 40 hours per week. The first chain-saw sharpening and repair required 7 hours of work, and an 80 percent learning curve is anticipated.
