Final answer:
The answer explains how to model the cost for a student attending a Halloween party at the Math Club based on the number of drinks bought using a cost function.
Explanation:
Cost Function Model:
The cost for a student attending the Halloween Party at the Math Club can be modeled as a function of the number of drinks bought. Each drink costs 5 soles, and the entrance fee is 15 soles. Therefore, the total cost 'C(x)' for 'x' drinks purchased can be represented as:
C(x) = 15 + 5x
Example:
If a student buys 3 drinks, the total cost would be C(3) = 15 + 5(3) = 15 + 15 = 30 soles.
