To represent the number of bracelets \( b \) Tonia can make with respect to the number of hours \( h \) she spends making them, you can use the following function notation:
\[ b(h) = 11h \]
Here, \( b(h) \) is the function that gives the number of bracelets made based on the hours \( h \) spent making them. Since Tonia makes 11 bracelets per hour, the equation clearly shows that the total number of bracelets is the product of 11 and the number of hours.
