In a history class, the probability of earning an A is times the probability of earning a B, and the probability of earning a C is times the probability of earning a B. Assuming that all grades are A, B, or C, how many B's will there be in a history class of students

The answer is 270 cars.you can do this by making a proportional relationship. for instance, 200 is the whole we are using, so on a “number line” 200 would be over 100%. now, since he sells 35% more, add 35% to 100% to get 135% on the other side of the “number line” on the bottom half, leaving the top half empty.cross multiply 200 by 135 then divide by 100 to get your answer. i hope this , if it did, , if you don’t mind, giving me brainiest! 200/100% } 200 • 135 /100 ? /135%

(x) - (y) = (1 + 4i)

(3 + 6i) - (2 + 2i) = (1 + 4i)
