Final answer:
Without additional context or a specific formula, we cannot determine the constant of variation for the given monetary values $27,576, $4,873, and $32,449.
Step-by-step explanation:
The constant of variation is a coefficient that represents the proportionality between two variables. In the context of the values given, we do not have enough information to determine a relationship or equation that would allow us to find a constant of variation. The provided values of $27,576, $4,873, and $32,449 are monetary and do not indicate a clear proportional relationship without additional context or a formula being applied. Therefore, based on the current information, it cannot be determined which answer choice between a) $0.5, b) $2, c) $4, or d) $6 is correct for the constant of variation.
