Answer:
20 Cookies
Explanation:
If Juan has 8 cookies and 8 cookies = 40%, multiply by 2. 16 = 80%. Now we only need 20% more and that will identify how much there are. To do this is just simply divide 8 by 2. 4 is our answer. It's half of 8 meaning half of 40%. So add 16 and 4, you get 20.
P.S
Have a Amazing Day!
