Question

a body builder consumed 4,400 calories yesterday. today, he consumed 3,600 calories. what is the percent decrease in number of calories consumed? round to the nearest percent. 18 %

Explanation:

Step1: Find the decrease in calories

Subtract today's calories from yesterday's: $4400 - 3600 = 800$

Step2: Calculate percent decrease

Use the formula $\text{Percent Decrease} = \frac{\text{Decrease}}{\text{Original Amount}} \times 100\%$. So, $\frac{800}{4400} \times 100\% \approx 18.18\%$, which rounds to $18\%$.

Answer:

18%
