Question

There were 45 athletes who came to practice yesterday and 30 students who came to practice today. Find the percent of change. Round to the nearest whole percent if necessary.

A) 50%
B) 33%
C) 67%
D) 150%

Answer 1

B) 33%. The percent of change is -33%, which means there was a decrease of 33% in the number of students who came to practice today compared to yesterday.

Step-by-step explanation:

To find the percent of change between two values, you can use the formula:

Percent of Change = ((New Value - Original Value) / Original Value) * 100

In this case, the original value is 45 (the number of athletes who came to practice yesterday) and the new value is 30 (the number of students who came to practice today). So the percent of change is:

((30 - 45) / 45) * 100 = -33.33%

Rounding to the nearest whole percent, the percent of change is -33%, which means there was a decrease of 33% in the number of students who came to practice today compared to yesterday.
