Researchers at a lake have determined that the percentage of fish in the lake that are intolerant to pollution can be estimated by the function P(W,R,A) = 45 - 1.89W - 1.29R - 1.16A where W is the percentage of wetland, R is the percentage of residential area, and A is the percentage of agricultural area surrounding the lake. Answer the questions below. a. Use this function to estimate the percentage of fish that will be intolerant to pollution if 3 percent of the land is classified as wetland, 16 percent is classified as residential, and 0 percent is classified as agricultural. (Note: The land can also be classified as forest land.) If 3 percent of the land is wetland, 16 percent is residential, and 0 percent is agricultural, percent of the fish will be intolerant to pollution. b. What is the maximum percentage of fish that will be intolerant to pollution? The maximum percentage is |percent. c. Which variable has the greatest influence on P? The variable has the greatest influence on P
