Question

You earn $56 walking your neighbor's dogs for 8 hours. Your friend earns $36 painting your neighbor's fence for 4 hours

Answer 1

An equation for your earnings is 56 = 8h
An equation for your friend's earnings is 36 = 4h 
To get your pay per hour divide each side by 8 to get $7 per hour.
To get your friend's pay per hour divide each side by 4 to get $9 per hour.  
Hope this helps!
