Question

THE NUMBER OF STUDENTS FRON SCHOOL LAST WEEK WAS 145. This week there were only 110 students sick. What was the percent decrease of the number of students home sick?

Answer 1

The percent decrease of the number of students home sick is 24.14%.

Solution:

The number of students home this last week was 145

This week there were only 110 students home sick

To find: Percent decrease

The percent decrease is given by formula:

`\text{Percent Decrease } = \frac{\text{Final value-initial value}}{\text{Initial value}} * 100`

Here given that,

Initial value = last week = 145

Final value = this week = 110

Substituting the values in formula, we get,

`\text{Percent Decrease } = (110-145)/(145) * 100\\\\\text{Percent Decrease } = (-35)/(145) * 100\\\\\text{Percent Decrease } = -24.14`

Here negative sign denotes decrease in percent

Thus the percent decrease of the number of students home sick is 24.14%.
