Question

Brian decided to start a dog-walking service. He's going to charge each dog owner $4.50 to walk one dog and $6.75 to walk two dogs. Approximately how much will he earn if he walks 13 single dogs and 9 sets of two dogs?

Answer 1

If Brian charges $6.75 per set of dogs, and he walks 9 sets, 9 times $6.75 is $60.75...

If we add those together we end up with $119.25

4.50 x 13= 58.50

6.75 x 9= 60.75
