Final answer:
To calculate the total homework questions assigned after 14 days, multiply the daily number of questions by 14. We use multiplication because Mr. Salazar assigns a fixed number of questions each day.
Step-by-step explanation:
The question concerns how to calculate the total number of homework questions assigned by Mr. Salazar after 14 days given the information that he assigns the same number of homework questions each school day. The correct answer to the question is a) 14 times the daily assignment, because if the same number of homework questions is assigned each day, the total after 14 days would simply be 14 multiplied by the number of questions assigned each day.
If we knew the daily number of homework questions, we could multiply this by 14 to get the total number. However, choices b) and c) would not be correct because they involve adding ratios or multiplying ratios, which does not apply to finding the total questions assigned over multiple days for a constant daily assignment. Choice d) is incorrect because the ratio for the 14th day would be the number of questions assigned that day, not the cumulative total.
