To determine Natalie's total calorie change, we need to calculate the calories burned from running and dribbling and then subtract the calories consumed from her granola bar, fruit, and juice.
Step 1: Calculate total calories burned
- Running: 157 calories
- Dribbling: 96 calories
Total calories burned = 157 + 96 = 253 calories
Step 2: Calculate total calories consumed
- Granola bar: 205 calories
- Piece of fruit: 31 calories
- Fruit juice: 34 calories
Total calories consumed = 205 + 31 + 34 = 270 calories
Step 3: Calculate total calorie change Total calorie change = Total calories burned - Total calories consumed Total calorie change = 253 - 270 = -17 calories
Thus, Natalie experienced a total calorie change of -17 calories. This means she consumed 17 more calories than she burned during practice.
