Answer:
40
Explanation:
The calculation of Permits remaining is shown below:-
New number of permits issued = Emits units of Pollutant × Remaining percentage
= 400 × (100% - 25%)
= 400 × 0.75
= 300
Permits remaining = New number of permits issued - Reduction in units
= 300 - 260
= 40
The company sells 40 permits
Therefore, for computing the permits remaining we simply applied the above formula.
