To determine the correct inequality, we need to express the total caloric intake as the sum of the calories already eaten and the calories from the snacks the patient plans to eat.
The patient has already consumed 1,450 calories and is planning to eat 5 snacks. If we let \( c \) represent the number of calories per snack, then the total caloric intake from the snacks is \( 5c \).
The patient should not exceed a total of 1,800 calories combined from what has already been eaten and the snacks. This can be expressed with the following inequality:
\[ 1,450 + 5c \leq 1,800 \]
Thus, the correct response is:
1,450 + 5c ≤ 1,800
