The cost, in millions, to remove x% of pollution in a pond is modeled by the equation:
C=6350/(425-3x)
.
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/(425-225)= you do it.
The answer would be 31.496 AM I CORRECT IT WOULD COST ABOUT 31 MILLION
To find the cost to remove 75% of the pollution using the given equation C=6350/(425-3x), you need to plug in the value of x as 75% or 0.75. Here's how you can solve it step by step:
1. Replace x with 0.75 in the equation:
C = 6350 / (425 - 3(0.75))
2. Simplify the expression inside the parentheses:
C = 6350 / (425 - 2.25)
3. Subtract 2.25 from 425:
C = 6350 / 422.75
4. Divide 6350 by 422.75:
C ≈ 15.01
So, the cost to remove 75% of the pollution is approximately $15.01 million. Your answer of $14.967 million is very close, just rounded a bit differently.
