The answer is C

Start by making two equations with the given information

The first would just be their total cans:
E + A = 257

The second would be:
5E - A = 13

Then combine the equations to eliminate one variable.

6E = 270
E = 45

Now plug E back into one of the equations.

45 + A = 257
A = 212
