A principal is organizing a field trip for more than 300 students. She has already arranged the transportation for 220 students. Each school bus has the capacity to transport 40 students. Which of the following inequalities could be used to solve for x, the number of school buses still needed to transport all of the students? A. 40x - 220 > 300
B. 40x + 220 > 300
C. 40x > 520
D. 40x > 300

B..I can’t explain it tho cause I’m horrible at explaining

In all honesty, there really is no “work” per say to show. mainly it’s just using the process of elimination. the question is asking which domain(s) would be the most appropriate for the function c(n). n is the number of observed vehicles so right away, 1, 2, and 3 can be eliminated.why? 1, 2 start in the negatives and therefore it is impossible to observe negative cars. so, #4 would be the best answer to the given problem.
