She should charge $ 5 for small dog and $ 10 for large dog.
Step-by-step explanation:
Given,
Leanne charges twice as much to walk a large dog as she does to walk a small dog.
Number of large dogs = 5
Number of small dogs = 10
She wants to make $ 100.
To find the charge of large dog and small dog for walk.
Let,
She charges $ x for small dog and $ 2x for large dog.
According to the problem,
5×2x + 10×x = 100
or, 20x = 100
or. x = 5
Hence,
She charges $ 5 for small dog and $ 2×5 = $ 10 for large dog.
