Answer:
The correct answer is B. N = st
Explanation:
1. Let's review the information given to us to answer the question correctly:
t = number of toothpicks received by each student
s = number of students
N = total number of students
2. Which equation can be used to find the total number of toothpicks, N, given out by the teacher for the project?
Total number of toothpicks for the project = number of toothpicks received by each student * number of students, replacing with the variables:
N = t * s = s * t
The correct answer is B. N = st
