To determine if the coach is correct, we first need to find out how many hotdogs and hamburgers were eaten.
-
Start with the total number of hotdogs and hamburgers:
- Total items = 35
- Hotdogs = 21
- Hamburgers = 35 - 21 = 14
-
Next, we calculate how many hotdogs and hamburgers were left:
- Hotdogs left = 5
- Hamburgers left = 3
-
Calculate how many were eaten:
- Hotdogs eaten = Total hotdogs - Hotdogs left = 21 - 5 = 16
- Hamburgers eaten = Total hamburgers - Hamburgers left = 14 - 3 = 11
-
Now, we can check the ratio of hotdogs eaten to hamburgers eaten:
- Hotdogs eaten : Hamburgers eaten = 16 : 11
Since the ratio matches the coach's statement of 16:11, the coach is correct.
Therefore, the answer is 1 (yes).
