To find the number of hours \( h \) that Mateo rented the bike, we can set up an equation based on the cost structure provided.
The total cost of renting the bike is made up of two components:
- A fixed charge of $13 to rent the bike.
- A variable charge of $4 for every hour \( h \).
Thus, the total cost \( C \) can be expressed as:
\[ C = 13 + 4h \]
Given that Mateo paid $37 in total to rent the bike, we can set up the equation:
\[ 13 + 4h = 37 \]
This equation can be used to find the number of hours \( h \) that Mateo rented the bike.
