Answer:
20 cookies
Explanation:
8 in 1.5 minutes
so we want to find how many in 3.75 minutes since 3 + 45/60 = 3.75
so then its 1.5*2 = 3 so 8*2 = 16 to get that 16 cookies in 3 minutes
then we still have .75 left so then divide 8/2 to get 4 cookies in 0.75 minutes
16+4 = 20
you can also just find how many in 0.25 minutes (15 seconds) you get 6/8
multiply that by 3.75/0.25 = 15 you get 15*(8/6) = 20
