Answer:

1. Michael ate 50% of the cookies, so the remaining cookies are 50% of the total. Let's denote the total number of cookies as T. So, after Michael ate his share, 0.5 x T cookies remained.

2. Robert then ate 50% of what was left, leaving only 50% of the cookies that were left after Michael ate. So, after Robert ate his share, 0.5 x 0.5 x T = 0.25 x T cookies remained.

3. We know that 14 cookies remained after Robert ate his share.

So, we can set up the equation 0.25 x T = 14 and solve for T:

T = 14/0.25 = 56

So, Uncle Joe made 56 chocolate chip cookies.

12 times 2 is 24, and 24 times 2 is 48, so there was 48 cookies
