Sabrina is going to rent a bicycle while on vacation. There are two rental companies she can choose from. The first company charges $10 plus a rate of $2 per hour until the bicycle is returned. The second company's rental charges can be represented by the equation 𝑐 = 3ℎ + 6 where c represents the rental cost and h represents the number of hours the bicycle is rented. If Sabrina plans to bicycle for 3 hours, what is the least amount she could pay in rental fees?

• $6

• $10

• $15

• $16
