Phytoremediation is the use of plant growth to purify pollutants from soil, water, or air. Suppose that a crop of brake ferns can remove 15 milligrams per square meter of a particular pollutant from the soil in 20 weeks. After, 20 weeks the ferns are harvested and a new crop is planted. If C represents the number of corps of brake ferns needed to phytoremediate soil contaminated with 170 mg per square meter of the pollutant down to healthy levels of 5 mg per square meter, which equation best models the situation ?
