Could you please help me. In Marbles-R-Us they sell marbles
in boxes. Zeeshan buys 9 bags, each containing q marbles. On
the way home he plays Mark and wins 9 more marbles. What is
the expression for this? Thank you.
Each of the 9 bags contains q marbles, so Zeeshan leaves the
Marbles-R-Us store carrying
9q
marbles.
He then plays Mark and wins 9 more marbles. So we add 9 to
9q and get
9q + 9
That will do for an answer. Maybe your teacher wants you to
use the distributive law in reverse to get
9(q + 1)
However 9q + 9 will do.
