The excess lifetime cancer rise R is a measure of the likelihood that an individual will develop cancer from a?

particular pollutant. The value of R for pollutant A can be calculated using the linear model R=kd, where k is a constant and d is the daily dose in parts per million. The constant k for pollutant A can be calculated using the formula k=(.139B)/w whwere B is the total number of cubic meters of air a person breathes in one day and W is a person's weight in kilograms. Find k for a person who breathes in 40 m^3 of air per day and weighs 85 kg.
