Q. Ver en espa\~{n}ol Maddie takes piano lessons at River Rock Arts Center, where she pays $25\$25 per lesson. The function C(p)C(p) represents the cost, in dollars, of pp piano lessons. What is the domain of C(p)C(p)?\newlinea) All Real Numbers\newlineb) all real numbers 00 to 2525\newlinec) a whole number 00 to 2525\newlined) all real numbers
  1. Identify Variable Context: Identify the variable and its context. C(p)=25pC(p) = 25p, where pp is the number of piano lessons.
  2. Consider Practical Application: Consider the practical application of the variable pp. pp represents the number of piano lessons, which must be a non-negative integer (you can't take a negative or a fractional number of lessons).
  3. Determine Possible Values: Determine the possible values of pp. Since pp is the number of lessons and you can't have a fraction of a lesson or a negative number of lessons, pp must be a whole number starting from 00.
