Suppose you must find the termperature in degrees Fahrenheit F when it is 15º C. You would solve the equation F = (9/5)C + 32 for F. Your next logical step would be F = (9/5)(15) + 32. Why?

A: Addition Property of Equality
B: Multiplication Property of Equality
C: Substitution Property of Equality
D: Division Property of Equality
