Answer: John's rate = $14
Step-by-step explanation:
Given: John's friend told him that he could earn $49 for handing out flyers at a local concert.
If he works a total of 3.5 hours, the equation [tex]3.5x=49[/tex] can be used to determine his hourly rate x.
Divide 3.5 on both the sides of the equation, we get
[tex]x=\frac{49}{3.5}=14\\\\\Rightarrow x=14[/tex]
Therefore, John's rate = $14
