Question

A body builder consumed 4400 calories yesterday. Today, he consumed 3600 calories. What is the percent decrease in the number of calories consumed? Round to the nearest percent.

Answer 1

The bodybuilder experienced an 18% decrease in caloric intake, calculated by finding the difference between the two intakes, dividing by the original intake, and then converting that number to a percentage.

Step-by-step explanation:

To calculate the percent decrease in the number of calories consumed by the bodybuilder, we subtract the second day's caloric intake from the first day's, then divide by the first day's intake and multiply by 100 to get a percentage.

Step-by-step Calculation:

1. Subtract today's intake from yesterday's: 4400 - 3600 = 800 calories.
2. Divide the difference by the original (yesterday's) intake: 800 / 4400 = 0.1818.
3. Multiply the result by 100 to get the percentage: 0.1818 * 100 = 18.18%.
4. Round to the nearest percent: Approximately 18% decrease.
