Let x equal the number of burrito platters and y be the number of taco platters.
Then based on the problem description, the following 2 equations can be made:
(5) (x) + (3) (y) = 233
(1) (x) + (1) (y) = 55
From the second equation: x = 55-y
Plugging in this value for x in the first equation gives:
5 (55-y) + 3y = 233
Solving for y:
275 - 5y + 3y = 233
275 - 2y = 233
2y = 275-233 = 42
y = 21
Since x is 55 - y, then x = 34
Answer: Burrito platter costs $34 per platter and the taco platter costs $21 per platter.
