Also, Thank you to everyone who has helped me understand how to do the other problems I posted. I am very grateful!
+2863 24 + 13 = 37.
24 is 45% of the total weight, and 13 is 26% of the total weight.
So them added together should be 71% of the total weight. MEANING:
37 = 0.71x
X is the total weight.
So we have to find 0.29x
0.29*(3700/71) = 15.1126760563380282
So (E)?
