Final answer:
Based on the calculation using the provided data, there would be 235,000 computer programming jobs in 2023 after an increase of 115,000 jobs every 7 years from 120,000 jobs in 2010. However, this answer is not reflected in the provided multiple-choice options, indicating a possible error in the question.
Step-by-step explanation:
To calculate the number of computer programming jobs in 2023 based on the given information, we need to determine how many times the job count has increased since 2010, the starting point with 120,000 jobs, and how it increases every 7 years by 115,000 jobs. The year 2023 is 13 years after 2010, which means that the number of increments is 13/7, which is equal to 1 full increment period with some remainder (since we can only count full 7-year periods). Therefore, we have one full increment of 115,000 jobs.
So, 120,000 (base count of jobs in 2010) + 115,000 (increase after one 7-year period) equals 235,000 jobs in 2023.
However, since the multiple-choice options do not contain this number, it seems there is a misunderstanding or an error in the question or answer choices. None of the provided options (a) 120,000 (b) 135,000 (c) 150,000 (d) 165,000 correctly represent the calculation based on the information given. Hence, the most accurate response can't be determined from the options provided.
