Answer:
8 + 2 * X = P
2 + 3 * X = C
Step-by-step explanation:
By means of the statement we have to:
Phillp case: "Charges $ 8 the first time he walks a dog and $ 2 per walk after that" that is:
P = 8 + 2 * X
Where X would be the number of walks.
Carrie case: "Charge $ 2 the first time he walks a dog and $ 3 per walk after that" That is:
C = 2 + 3 * X
Where X would be the number of walks.
Therefore the equation system would be:
8 + 2 * X = P
2 + 3 * X = C
P and C earnings of Phillp and Carrie respectively.
