Write and solve a system of equations to solve the problem.
At a film festival, Film A is 4 times as long as Film B. Together, the films are 160 min long. How long is each film?

A. A + B = 160; 4A=B
Film A: 30 min, Film B: 130 min
B BA 12. am B: 32 min

B. B+A= 160; 4B = A
Film A: 128 min. Film B: 32 min

C. AB = 160; 4A=B
Film A: 40 min, Film B: 120 min

D. A = 4 A+ B = 160
