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

Answer 1

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

Answer 2

1840

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.

`\text{Net calories}=\text{Calories Eaten}-\text{Calories Burned}`

`\text{Net calories}=(560+770+990)-270-80-130`

`\text{Net calories}=2320-480`

`\text{Net calories}=1840`

Therefore, the net calories for a person is 1840.
