Your grade in algebra class is a function of how many proficient scores you earn. This function is represented by g(x), where x represents the number of proficient scores and g(x) represents your grade percentage. Explain what g(16) = 85 means in context.

• A grade of 16 means there were 85 proficient

• If I earn 16 proficient scores then my grade will be an 85%

• g is 5.3

• If I earn 85 proficients I will get a 16%
