Some diseases (such as typhoid fever) are spread largely by carriers, individuals who can transmit the disease but who exhibit no overt symptoms. Let x and y denote the proportions of susceptibles and carriers, respectively, in the population. Suppose that carriers are identified and removed from the population at a rate ß, so dy = -By. (1) dt Suppose also that the disease spreads at a rate proportional to the product of x and y; thus dx — аху. (2) dt a) Determine y at any time t by solving equation (1) subject to the initial condition y(0) = yo- y(t) = |Choose one b) Use the result of part (a) to find x at any time t by solving equation (2) subject to the initial condition x(0) = xo- %3D x(t) = |Choose one c) Find the proportion of the population that escapes the epidemic by finding the limiting value of x as t → o. As t - 0, the proportion of the population that escapes the epidemic is given by Choose one
