At a depth of h meters below the surface, the estimated total pressure P1, in kilopascals (kPa), a diver experienced is given by P1 =10h ＋101, which is a combination of estimated water pressure and estimated atmospheric pressure. After maintaining a certain depth, the diver descended d additional meters. The estimated total pressure P2, in kPa, the diver experienced after descending these d additional meters is given by P2 = 10d ＋311. Which of the following is the best interpretation of 311 in this context?

A certain open star cluster contains M-type stars and K-type stars. The estimated total mass of M-type and K-type stars in this open star cluster is 120,134 quettagrams. The graph shown models the possible combinations of the number of M-type stars, x, and K-type stars, y, that could be in this open star cluster if all the M-type stars have the same estimated mass and all the K-type stars have the same estimated mass. Based on the graph, which of the following is closest to the estimated mass, in quettagrams, of each M-type star in this cluster?
