A golf driver range charges a flat fee of $20 to practice and then $5.75 for a bucket of balls. Write an equation that models the charges (C) in terms of the number of bucket of balls (b) that you use

C=5.75b+20
C=20b+5.75
b=5.75C+20
b=20C+5.75
b=5.75C-20

1 answer

The correct equation that models the charges (C) in terms of the number of buckets of balls (b) used is:

\[ C = 5.75b + 20 \]

In this equation, \(C\) represents the total charges, \(b\) represents the number of buckets of balls, $5.75 is the cost per bucket of balls, and $20 is the flat fee for practice.
