Give the step-by-step reasoning process and then the final answer. Two apartment roommates split the rent, utilities, and grocery payments equally each month. The rent for the whole apartment is $1100 and utilities are $114. If one roommate pays $757 in all, how many dollars are groceries for the whole apartment?
Rent plus utilities for the whole apartment is 1100 + 114 = $1214. If one roommate pays $757 in all, the total cost of everything is 757 * 2 = 1514. The groceries cost 1514 - 1214 = 300.
The final answer: 300.
