The Dapdap tree in the Philippines is prone to wasp infestation. Suppose that the percent P of defoliation is approximated by P= 300/3+17e^-0.0625xwhere x is the number of egg masses in thousands. If the percent of defoliation is 20%, approximately how many egg masses are there?

Suppose that lo and I denote the light intensity before and after going through a material. Then according to Beer-Lambert's law"', x = -In () where k is a constant that depends on the material. If k = 0.03 and lo = 15 lumens, find the line intensity at a depth of 30 feet.
