Final answer:
The correct equation to represent the relationship where breakfast bars have 150% as much protein as sugar is P = 1.5S. The options provided seem to have a typo, none matches exactly, but option (C) may be a misprint for the correct equation.
Step-by-step explanation:
The question asks to find the equation that represents the relationship between the protein content and the sugar content of breakfast bars from a cereal company, given that the bars have 150% as much protein as they do sugar. The equation which accurately represents this relationship is P = 1.5S, where P stands for protein and S stands for sugar.
The correct option is not listed directly in the choices provided, suggesting the possibility of a typo. However, looking at the options given, if we interpret option (C) as P = 1.5S instead of p = 0.15s, it would most closely reflect the relationship described.
