Question

mr. adagio counted 30 students at last weeks art club meeting. this week, there are also drama auditions, so he expects 60% fewer students to attend. mr. adagio wants to know how many students to expect at this weeks art club meeting. how can you find the number of students expected at this weeks meeting? this weeks attendance = last weeks attendance? 60% of ?

Explanation:

Step1: Understand the problem

We know last week's attendance is 30, and this week there are 60% fewer students. So we need to find 60% of last week's attendance and subtract it from last week's attendance.

Step2: Determine the operation

The formula should be this week’s attendance = last week’s attendance - 60% of last week’s attendance. So the first blank is " - " (subtract) and the second blank is "last week’s attendance".

Step3: Calculate (optional for the formula part)

First, find 60% of 30: $0.6\times30 = 18$. Then subtract from 30: $30 - 18 = 12$. But for the blanks, we just need the operation and the value.

Answer:

The first dropdown should be filled with " - " (subtract) and the second dropdown should be filled with "last week’s attendance" (or 30, but since it's a general formula, "last week’s attendance" is better). So the formula is this week’s attendance = last week’s attendance - 60% of last week’s attendance.
