20%

Explanation:

Answer 2

Answer: The number of calories increased by 20%.

Explanation:

Given : The doctor recommended that Mike increase the number of calories he burns working out from 1,500 to 1,800.

Previous number of calories he used to burn = 1,500

Increase in calories = 1800-1500=300

Now , the percent increase in calories =
`\frac{\text{Increase in calories}}{\text{previous calories}}*100`

`=(300)/(1500)*100=20\%`

Hence , the number of calories increased by 20%.
