Question

Mr.Anderson hired a lawn service company who charged a one time service fee of $50 plus $40 per hour. His total bill came out to $250. Write an equation and then solve

Answer 1

`\begin{gathered} 40t+50=250\text{ where t is the time in hours} \\ 40t+50=250\rightarrow \\ 40t=250-50=200\rightarrow \\ 40t=200\rightarrow t=(200)/(40)=5\text{ hours} \end{gathered}`
