Research suggests that the probability of a certain fuse malfunctioning increases exponentially as 1) the concentration of an impurity in the fuse increases. The probability is modeled by the function y = 4(257,911)x, where x is the impurity concentration, and y, given as a percent, is the probability of the fuse malfunctioning. Find the probability of the fuse malfunctioning for an impurity concentration of 0.12. Round to the nearest percent.
