Joseph has $m. Kenny has 3 times as much money as Joseph. Leo has half the amount of money Joseph and Kenny has altogether. How much money do the 3 boys have altogether?
Solution
Joseph ----- $m
Kenny ----- 3 x $m = $3m
Joseph and Kenny ----- $m + $3m = $4m
Leo ----- $4m divided by 2 = $2m
Total ----- $4m + $2m = $6m
Answer: They had $6m altogether.
