Question

A robot is expected to filter pollution out of at least 350 liters of air and water. It filters air at the rate of 50 liters per minute, and it filters water at the rate of 20 liters per minute.

Write an inequality that represents the number of minutes the robot should filter air (A) and water (W) to meet this expectations

Answer 1

50A+20W≥350

Explanation:

Answer 2

`20W+50A\geq 350`

Explanation:

we are given that A robot is expected to filter pollution out of at least 350 liters of air and water.

Also It filters air at the rate of 50 liters per minute, and it filters water at the rate of 20 liters per minute.

The inequality for number of minutes the robot should filter air (A) and water (W) to meet this expectations can be writte as follows:

`20W+50A\geq 350`

Hence the required inequality has been formulated.
