Marcus and his family are planning a vacation that involves horseback riding. Horseshoe Ranch charges a $12.95 ranch entrance fee plus $14.95 per hour to rent horses.

To calculate the total cost of horseback riding at Horseshoe Ranch, we need to consider the entrance fee and the hourly rental fee.

Let's assume Marcus and his family plan to ride horses for x hours.

The total cost of renting horses for x hours would be 14.95 * x.

So, the total cost of horseback riding would be the sum of the entrance fee and the rental fee: 12.95 + (14.95 * x).
