happy paws charges 21.00 plus 3.50 per hour to keep a dog during the day. Woof watchers charges 10.00 plus 4.75 per hour. Complete the equation and solve it to find for how many hours the total cost of services is equal. Use the variable h to represent the number of hours

Answer: 8.8 hours

Explanation:

To start off, we’ll make an equation that “connects” both companies:

10 + 4.75h = 21 + 3.5h (we put h to represent the number of hours)

Move all similar terms to one side:

4.75h - 3.5h = 21 - 10

Simplify:

1.25h = 11

h = 8.8


I hope this helps!
