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

Given,

Charge to walk one dog = $4.50

Charge to walk two dogs = $6.75

Number of single dogs = 13

Set of two dogs = 9

To find,

His total earnings.

Solution,

We can simply solve this mathematical problem by using the following mathematical process.

Earnings from single dogs = 4.50 × 13 = $58.50

Earnings from sets of two dogs = 6.75×9 = $60.75

Total earnings = 58.50+60.75 = $119.25

Hence, his total earnings is $119.25

Answer 2

multiply 13 by charge for one dog and 9 by charge.

13 * 4.50$+9 * 6.75$ =

58.5 60.75 = 119.25$ +

He will earn about 120$.
