Question

Jane likes to exercise daily. The table shows the number of calories y she burns by exercising steadily for x minutes. How many calories would she burn by exercising for 29 minutes?

Answer 1

Do you have a picture of the table?

Answer 2

319 cal/min.

Explanation:

The table is attached.

You can observe in the table that there's no a value for 29 minutes.

That means we need to find the linear expression and then calculate the answer.

First, we need to find the ratio of change using two pairs of the given table and the following formula, (20,220) and (40,440) are the points

`m=(440-220)/(40-20)=(220)/(20) =11`

The ratio of change states that Jane burns 11 calories per minute. So, after 29 minutes, she will burn

`11cal(29min)=319 cal/min`
