Question

You can buy a skateboard for $48 from a friend and rent the safety equipment for $2.50 per hour.  Or you can rent all items you need for $6.50 per hour.  How many hours must you use the skateboard to justify buying your friends skateboard?

Answer 1

`\begin{gathered} \text{The first equation is,} \\ \text{price}_1=48+2.5h \\ \text{The second equation is,} \\ \text{price}_2=6.5h \\ So,\text{ equate both the equation,} \\ 6.5h=48+2.5h \\ 4h=48 \\ h=12\text{ hours} \end{gathered}`
