You know when for example they have the same variable or if there is no variable then you could combine them.For example, if it is 3x and 5x you could combine it to get 8x but if it is like 3x and 2y, you can’t combine it since it doesn’t have the same variable

Answer:
22 per dog when she is walking 8
she would make 176 for walking all 8 of them
Step-by-step explanation:
For each additional dog she walks she is giving a discount. If you subtract each one you will see she is giving a 2.75 discount.
40-37.25 = 2.75
37.25-34.50 = 2.75
34.50-31.75 = 2.75
Since you know she gives a discount of 2.75 per dog you can take that times the number of dogs (8).
8 x 2.75 = 22 per dog
Then take that amount and multiply it by the number of dogs she is walking.
8 x 22 = 176 for all 8 dogs
