3. Mr. Wilk is a high school math teacher whose salary is \( \$ 33.660 \) for this school year, which has 180 days. In Mr. Wilk's school district, substitute teachers are paid \( \$ 85 \) per day. If Mr. Wilk takes a day off without pay and a substitute teacher is paid to teach his classes, how much less does the school district pay in salary by paying a substitute teacher instead of Mr. Wilk for that day?

To find out how much less the school district pays in salary by paying a substitute teacher instead of Mr. Wilk for that day, we need to calculate the difference between Mr. Wilk's daily salary and the substitute teacher's daily salary. Given: - Mr. Wilk's annual salary: $33,660 - Number of days in the school year: 180 - Substitute teacher's daily salary: $85 First, let's calculate Mr. Wilk's daily salary: \[ \text{Mr. Wilk's daily salary} = \frac{\text{Annual salary}}{\text{Number of days in the school year}} \] \[ \text{Mr. Wilk's daily salary} = \frac{33660}{180} \] Now, we can calculate the difference between Mr. Wilk's daily salary and the substitute teacher's daily salary to find out how much less the school district pays in salary by paying a substitute teacher instead of Mr. Wilk for that day. Calculate the value by following steps: - step0: Calculate: \(\frac{33660}{180}\) - step1: Divide the terms: \(187\) The daily salary of Mr. Wilk is $187. Now, let's calculate the difference between Mr. Wilk's daily salary and the substitute teacher's daily salary: \[ \text{Difference} = \text{Mr. Wilk's daily salary} - \text{Substitute teacher's daily salary} \] \[ \text{Difference} = 187 - 85 \] Let's calculate the difference. Calculate the value by following steps: - step0: Calculate: \(187-85\) - step1: Subtract the numbers: \(102\) The school district pays $102 less in salary by paying a substitute teacher instead of Mr. Wilk for that day.
