Raul is selling coupon books. He started with 50 coupon books and has already won a prize for selling at least 10 coupon books. The total amount of money Raul will make from selling x coupon books is represented by a function.

f(x)=20xf(x)=20x



What is the practical domain of the function if Raul sells 50 coupon books?
