some ? i think its around 75.00 but i'm no good at math.

He will earn about $120  if he walks 13 single dogs and 9 sets of two dogs .

Step-by-step explanation:

Given : Brian's going to charge each dog owner $4.50 to walk one dog and $6.75 to walk two dogs.

If he walks 13 single dogs , then amount earned = 13 × $4.50

= $58.5                             (1)

If he walks 9 sets of two dogs, then amount earned = 9  × $6.75

=$60.75                             (2)

Add (1) and (2)

The total amount he earned =  $58.5 + $60.75              

= $119.25 ≈ $120

Hence, he will earn about $120  if he walks 13 single dogs and 9 sets of two dogs .
