Question 475206: 1. The cost, in millions of dollars, to remove x % of pollution in a lake modeled by c=6000/200-2x x=75%. should I substitute 75 for x or .75 for x? Answer by richard1234(7193) (Show Source):
You can put this solution on YOUR website! Substitute 75, because the function involves x% (e.g. substitute all occurrences of x in the sentence with 75). Also, if x ranged from 0 to 1.00, the cost hardly changes. Does that make sense?
