The cost, in millions, to remove x% of pollution in a pond is modeled by the equation:
C=6350/(4253x)
.
What is the cost to remove 75% of the pollution?
Hint: Plug in and calculate, do not convert to a decimal.
Can someone tell me how figure this out step by step recheck my answer PLEASEEEEEE!!! I tried to recheck AND IT DIDN'T COME UP WITH SAME Answer due tommorrow help me please
cost = 6350/(425  3(.25)) =$ 14.967
it would cost about $15 million

you should have 75 in the denominator, not .25
cost = 6350/(425225)= you do it. 
The answer would be 31.496 AM I CORRECT IT WOULD COST ABOUT 31 MILLION
