Final answer:
The bear ate 700 items in total, but without the specific calorie count of each item, we cannot determine the exact number of calories consumed. The bear's calorie intake is unknown.
Step-by-step explanation:
When determining how much the bear ate, we simply add the number of hamburgers (500) to the number of chicken fingers (200). Therefore, the bear ate a total of 700 items. As for the number of calories consumed, unless the calorie content of each hamburger and chicken finger is provided, we cannot accurately calculate the total calorie intake. Fast food meals such as hamburgers and chicken fingers are known to be high in calories, and a typical fast-food cheeseburger can have around 540 Calories, which are actually kilocalories. As meals high in fat have a higher energy density, a typical fast food meal can contain a significant portion of the daily recommended caloric intake for humans, making it easy to exceed one's calorie recommendation for the day with just one meal.
