Viefleur [7K]

Answer: The number of calories increased by 20%.

Step-by-step 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 = $\dfrac{\text{Increase in calories}}{\text{previous calories}}\times100$

$=\dfrac{300}{1500}\times100=20\%$

Hence , the number of calories increased by 20%.
