The total cost to rent a row boat is $18 times the number of hours the boat is used. Write an equation to model this situation if c = total cost and h = number of hours.

c – 18 = h

h = 18c

c = 18h

1 answer

The equation that models the total cost to rent a rowboat, based on the description provided, is:

\[ c = 18h \]

This means that the total cost \( c \) is equal to 18 times the number of hours \( h \) the boat is used.
