Guide Questions To Answer the Problem

What is asked in the problem meaning what are we looking for?
What are the given facts or the known variables?
What operation to be used or this is the arithmetic operation that we need to use to solve the problem.
What is the number sentence or we are tasked to create a mathematical model to help us solve the problem.
What is the answer or the conclusion of the problem?

Let's answer each question and make a conclusion about the problem.

Question (a): What is asked?

We are supposed to solve for the number of students who didn't attend the orientation.

Question (b): What are the given details?

There are 1485 students in the said school and 80% of them attended the orientation. This means to say that to solve for the actual number of students who attended the orientation, simply multiply 1485 by 0.80. The operation used will be the answer to the next question.

Question (c): What operation will be used?

From Question (b), we will use multiplication to know the number of students who attended the orientation, and we will use subtraction to know the number of students who did not attend the orientation.

Question (d): What is the number sentence?

From the clues in Question (b) Question (c), we can formulate the number sentence or mathematical model.

Let $x$ be the number of students who didn't attend the orientation.

So, since we know that the number of students who attended the orientation is the product of 1485 by 0.80, then we have 1188 students who actually attended the orientation.

So the mathematical model or number sentence is given by

$x = 1485(1-0.80)$ or $x = 1485 - 1188$ . Either of the number sentences works.
