1 Carlos provides dog-walking services in his neighborhood. For each walk he charges a flat fee of \( \$ 5 \) for clean-up and \( \$ 6 \) per dog. Write an equation to represent the relationship between the total charge, \( c \), and the number of dogs he walks, \( d \).
c = 5 + 6d
Step 1 :c = 5 + 6d
