Question

Avery baked some cookies. He gave 6 to his friend and shared the rest with his sister. Write an algebraic expression to represent this situation. ( Remember to define the variable(s) )

Answer 1

If y are the cookies he baked and x are the cookies he shared with his sister:
$y = 6 + x$
You could also express this as a function (i dont know your school grade, so i dont know if you have been taught this):
$f(x) = 6 + x$
if you haven't been taught functions, then just ignore this
