You are checking the results of a phone app that counts calories. When someone eats, it is recorded as positive calories. When someone exercises, it is recorded as negative calories. What is the number of net calories for a person with the following record? Description Calories Bike, 30 min -270 Breakfast 560 Lunch 770 Walk, 45 min -80 Dinner 990 Ping-pong, 30 min 130

Respuesta :

1840 calories. I might be wrong so don't rely on me 100%. Sorry.

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.
