Answer 1

`\begin{gathered} a\text{. the labor was} \\ 15.4*45=693\text{ } \\ \\ \text{ The labor cost was \$693} \\ \\ b\text{. The repair bill was} \\ \\ 693+857.46=1550.46 \\ \\ \text{ The repair bill was \$1550.46} \\ \\ \end{gathered}`
`\begin{gathered} C.\text{ We work 14 hours per day. Since the tractor was in the shop }2(1)/(2)\text{ days, then we lost } \\ \\ \\ 14\cdot2+(14)/(2)=28+7=35\text{ hours of work, } \\ \\ We\text{ lost } \\ 35\cdot12=420 \\ \\ \text{ we lost \$420 by not having the use of the tracctor.} \\ \\ D.\text{ The breakdown actually cost} \\ \\ 420+1550.46=1970.46 \\ \\ \text{ The breakdown actually cost \$}1970.46 \end{gathered}`
