ALG2 Unit 1 How to write the inequality from a word problem

The video tutorial explains how to model the number of regular and super-sized containers an air cargo plane can transport using an inequality. It begins by identifying the problem and the variables involved, X for regular containers and Y for super-sized containers. The tutorial discusses how one super-sized container takes up the space of three regular containers and guides viewers through formulating an inequality to represent this relationship. The video concludes with a summary and addresses any questions.

What is the maximum number of regular containers an air cargo plane can transport?

• 10

• 15

• 20

• 25

How many regular containers' space does one super-sized container occupy?

• Two

• Three

• Four

• Five

Which variables are used to represent the number of regular and super-sized containers?

• X and Y

• P and Q

• M and N

• A and B

What is the inequality that models the number of containers the plane can transport?

• X + 3Y ≥ 15

• X + 3Y < 15

• X + 3Y > 15

• X + 3Y ≤ 15

If a plane carries 3 super-sized containers, how many regular containers can it still carry?

• 6

• 0

• 9

• 3
