To determine how many hours Melanie can rent the bike without exceeding her budget of $50, we can set up an inequality based on the cost of renting the bike.
The total cost \( C \) of renting the bike is given by the formula: \[ C = 8h + 6 \] where \( h \) is the number of hours she rents the bike.
Since Melanie wants to spend less than $50, we need to set up the inequality as follows: \[ 8h + 6 < 50 \]
This inequality represents the condition that the total cost must be less than $50.
So, the correct response is: 8h + 6 < 50
