The exponential function P = 300 × 0.88m gives the amount in parts per million of PCBS in a contaminated site m months after a cleanup process begins. (a) What is the weekly decay factor? Assume there are four weeks in each month. (Round your answer to two decimal places.) Find a formula that gives the amount P in parts per million w weeks after cleanup begins. Op- 300 x 3.52" Op = 300 x 0.97W Op- 300 x 0.22" Op = 300 x 0.60w Op = 300 x 0.94w (b) What is the yearly decay factor? (Round your answer to two decimal places.) Find a formula that gives the amount P in parts per million y years after cleanup begins. Op= 300 x 5.28 O p = 300 x 0.99Y Op- 300 x 0.07Y OP = 300 x 10.56Y OP - 300 x 0.22
