Question
- a swimming pool company charges a one - time fee of $500 plus $50 per month for maintenance. if m represents the number of months of maintenance, which equation represents the total cost c of maintaining the pool?
a. $c = 50m - 500$
b. $c = 500 + 50m$
c. $c = 500m$
d. $c = 450m$
Step1: Analizar el costo fijo y variable
El costo fijo es \$500 (una vez) y el costo variable es \$50 por mes. Si \( m \) es el número de meses, el costo variable total es \( 50m \).
Step2: Formular el costo total
El costo total \( C \) es la suma del costo fijo y el costo variable. Entonces, \( C = 500 + 50m \).
