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:

$\text{Percent Decrease } = \frac{\text{Final value-initial value}}{\text{Initial value}} \times 100$

Here given that,

Initial value = last week = 145

Final value = this week = 110

Substituting the values in formula, we get,

$\text{Percent Decrease } = \frac{110-145}{145} \times 100\\\\\text{Percent Decrease } = \frac{-35}{145} \times 100\\\\\text{Percent Decrease } = -24.14$

Here negative sign denotes decrease in percent

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