The senior class at Rivermont High School rented and filled 11 vans and 3 buses with 283 students. The senior class at Washington High School rented and filled 12 vans and 14 buses with 770 students. Which system of equations solves this problem to show how many students were in each van and each bus?
11v + 3b = 283
12v + 14b = 770
v + b = 14
v + b = 16
11v + 12v = 283
3b + 14b = 770
v + b = 30
23v + 17b = 1053
