Question

david kalb started a pet-walking business , he charges $20 to walk one dog, twice a day. He walks six dogs five days a week for four customers. He walks three dogs seven days a week for three other customers. How much money does David get from his customers each week? If his weekly expenses are $350, what is the profit?

Answer 1

6 dogs $20 each is $120 per day. $120 per day times 5 is $600. 3 dogs $20 each is $60 per day. $60 per day times 7 is $420. $600+ $420 is $1020 per week. $1020 - $350 is $670 profit per week after expenses.

Answer 2

Answer:

David earns $1,020 a week, and his weekly profit is $670.

Step-by-step explanation:

Since David walks six dogs per day, and each dog is $20, he earns a total of $120 per day from those six dogs. Also, knowing that he walks the six dogs five days a week, he earns $600 from walking the six dogs for five days per week alone. Using this same logic for the three dogs he walks seven days a week, we can conclude that he gets $60 from walking those three dogs. Knowing he walks those three dogs seven days a week, he gets $420 from walking those three dogs. Combining the totals gives us $1,020, the amount of money he earns per week. Since his weekly expenses are $350, we subtract that from $1,020 to get his weekly profit: $670.
