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?

$55.00
$75.00
$100.00
$128.00
Some help? I think its around 75.00 but I'm no good at math.

Answer 1

`multiply\ 13\ by\ charge\ for\ one\ dog\ and\ 9\ by\ charge\ by\ two\ dogs\\\\13*4.50\$+9*6.75\$=\\\\58.5+60.75=119.25\$\\\\ He\ will\ earn\ about\ 120\$.`

Answer 2

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

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 .
