The cost c, in dollars, to remove p percent of a certain pollutant from a pond is estimated by using the formula c=100,000p/100-p. according to the estimate, how much more would it cost to remove 90% of the pollutant from the pond than it would cost to remove 80% of the pollutant? (a) $500,000 (b) $100,000 (c) $50,000 (d) $10,000 (e) $5,000

(A) $500,000

Step-by-step explanation:

Given formula for finding the cost ( in dollars ) to remove p percent of a certain pollutant,

If P = 90,

If P = 80,

∵ 900000 - 400000 = 500000,

Hence, it will cost $500,000 more to remove 90% of the pollutant from the pond than it would cost to remove 80% of the pollutant,

Option '(A)' is correct.
