Answer:
12 full cookies or 12 2/3 of a cookie
Step-by-step explanation:
9 1/2 = 19/2
19/2= 38/4
38/4 / 3/4
38/4 time 4/3
38/3
12 2/3
So for these problems you just need to get all x values on one side of the equal sign. Since this has just an x and not other x values we can leave the x there on the left. Now subtract 5 on both sides to get rid of the 5 on left side of the equals sign. Subtract 5 on the right side too because anything that you do on the left side, you do on the right side as well. It should look like this now:

P </= -3 .......... put like that
10 times 11% is 11 dollars, so 11 times 10 equals 110. Then 110 plus 100 equals 210. So you'd have $210 after ten years with 11 percent interest.
