Question

Michelle ate 1/2 of a burrito and an entire salad for dinner. The salad contained 50 calories, and the entire meal contained 1300 calories. Which equation can determine c, the number of calories in the burrito?

Option 1: c = 1300 - 50
Option 2: c = 1300 + 50
Option 3: c = 1300 × 50
Option 4: c = 1300 ÷ 50

Answer 1

To find the number of calories in the entire burrito (c), subtract the calories of the salad from the total meal calories and then multiply by 2 because Michelle only ate half of the burrito. The equation is c = (1300 - 50) × 2.

Step-by-step explanation:

To determine c, the number of calories in the burrito, we need to subtract the calories of the salad from the total calories of the meal. Since Michelle ate 1/2 of a burrito and an entire salad for dinner, where the salad contained 50 calories, and the entire meal contained 1300 calories, the correct equation to find the calories in the whole burrito will be:

Option 1: c = 1300 - 50

This equation suggests that we subtract the 50 calories from the salad from the total calories of the meal to find the total calories in the whole burrito. Then, since she only ate half of the burrito, you would have to multiply c by 2 to find the calories for the full burrito, so the final equation would be:

c = (1300 - 50) × 2

This will give you the number of calories in the entire burrito, not just the half.

Remember that calories contained within food are actually kilocalories (kcal), meaning that when a food label says 1300 Calories, it's equivalent to 1300 kcal.
