The inequality would be CO2 > 1,000 ppm.

To write an inequality to show the amount of carbon dioxide (CO2) in parts per million (ppm) that would cause drowsiness and complaints of stale air, we need to express that the CO2 concentration must not be greater than 1,000 ppm.

Inequality: CO2 ≤ 1,000 ppm

This inequality states that the concentration of CO2 should be less than or equal to 1,000 ppm to avoid drowsiness and complaints of stale air.

To write an inequality showing the amount of carbon dioxide (CO2) in parts per million that would cause drowsiness and complaints of stale air, you would use the symbol ">" (greater than).

The inequality would be: CO2 > 1,000 ppm.

This means that if the amount of CO2 in the workplace exceeds 1,000 ppm, it would result in drowsiness and complaints of stale air.
