Answer:
1840
Step-by-step explanation:
The records of calories for a person is shown below:
Description Calories
Bike, 30 min -270
Breakfast 560
Lunch 770
Walk, 45 min -80
Dinner 990
Ping-pong, 30 min 130
We need to find the number of net calories for a person with the following record.
[tex]\text{Net calories}=\text{Calories Eaten}-\text{Calories Burned}[/tex]
[tex]\text{Net calories}=(560+770+990)-270-80-130[/tex]
[tex]\text{Net calories}=2320-480[/tex]
[tex]\text{Net calories}=1840[/tex]
Therefore, the net calories for a person is 1840.
