Will mark brainliest question in the pic.

Autility company burns coal to generate electricity. the cost c(p), (in dollars) of removing p percent of the some stack pollutants is given by c(p)= 85000p/100-p a) find the cost to remove 30% of the pollutant b) find where the function is undefined

Which simplifys to a+ b? a-(1-b)+1 -(1-a)-b+1 (a--1) -1)+1
