1160 calorie intake with 2 hours of gymnastics and 1 hour of aerobics. how many calories not used? (*hint - subtraction)
0 calories
5 calories
10 calories
15 calories

Explanation:

Step1: Calculate calories used in gymnastics

Calories used in 2 - hour gymnastics: $2\times400 = 800$ (since 1 - hour gymnastics uses 400 calories)

Step2: Calculate calories used in aerobics

Calories used in 1 - hour aerobics: 300 (from the table)

Step3: Calculate total calories used

Total calories used = Calories used in gymnastics+Calories used in aerobics = $800 + 300=1100$

Step4: Calculate calories not used

Calories not used = Calorie intake - Total calories used = $1105-1100 = 5$

Answer:

5 calories
