A water park charges a one-time membership fee of $25. It allows members to visit for a reduced price of $5 per day. Write an equation to represent the cost, c, for a member to visit the waterpark for a certain number of days, d.

1 answer

To represent the total cost \( c \) for a member to visit the water park for \( d \) days, you can use the following equation:

\[ c = 25 + 5d \]

In this equation:

  • \( 25 \) is the one-time membership fee.
  • \( 5d \) represents the cost of visiting the water park for \( d \) days at the rate of $5 per day.
