The answer is $48.56 because in the question it states they, split it evenly getting $24.28 each, since there is 2 people who split it you just multiply $24.28 by 2.
850. If there is 17 red beads for every 150 beads Then you would divide 7500 by 150 and you get 50. Then multiply 50 with 17 and your answer is 850 red beads. 7500/150=50. 50 x 17= 850.
