Ben will have 2 less candies than Charlie. Debra wiill get the most amount of candies. Elle will have 3 times as many candy as Ben. How can Sally split the candies between her friends?

A = Amy; B= Ben; C=Charlie; D=Debra; E=Elle A=2B, C=B+2; D=A+1=2B+1; E=3B A+B+C+D+E=48 2B+B+B+2+2B+1+3B = 48 9B+3=48 9B=45 B=45/9=5 A=2(B)= 2(5)=10 C=B+2=2+5=7 D=2B+1=2(5)+1=11 E=3B=3(5)=15
