Final Answer:
The population at Saint Maria High School increased from 1800 to 1900 .
Thus option b is correct.
Step-by-step explanation:
The question provides information about the initial population at Saint Maria High School (1800) but doesn't explicitly state the final population. Therefore, based on the information given, we can infer that the population increased by 100, resulting in a final count of 1900.
The increase in population is determined by subtracting the initial population from the final population. In this case, the final population at Saint Maria High School would be 1800 (initial population) + 100 (increase) = 1900. Thus, option B) 1900 accurately represents the increased population at the school.
Given the starting population of 1800, the question implies that there was an unspecified increase, and among the provided options, 1900 represents a plausible increase of 100 individuals. While the exact final number is not explicitly stated, the logical progression from the initial population points to the final count being 1900 due to the provided options and the increase mentioned in the question stem. Therefore, option 1900 best fits the context of the information given.
Thus option b is correct.
