Answer:
½j + 7
Explanation:
j = jelly beans
Jarrett splits his bag of j jelly beans into two equal piles
so now we have two equal piles of the jelly beans
½j and ½j
and gives one pile to his brother
so right now the brother has
½j
He then gives his brother seven more beans
we add 7 to our equation and now
this is the algebraic expression that represents the number of beans the brother has:
½j + 7
