Answer:
105 cookies
Explanation:
We can model Karen's cookie situation like so:
#TotalCookies = #RecentlyBought + #AlreadyHad
We know that Karen already had 9 cookies in a jar, so it now looks like.
#TotalCookies = #RecentlyBought + 9
The number she recently bought, involves multiplication. So she bought 6 bags of 16 cookies. That's 6 x 16 = 60 + 36 = 96
#TotalCookies = 96 + 9 = 105 cookies
Karen loves cookies!
