Answer:
There will be only 1 cookie (40th one) which contains both icing and sprinkles.
Step-by-step explanation:
Given:
Number of cookies baked = 4 dozens.
1 dozen = 12 cookies
4 dozens = [tex]12\times4 =48\ cookies[/tex]
Chocolate icing on 8 cookie.
Sprinkles on 5 cookie.
We need to find the number of cookies which will have both icing and sprinkles.
Solution:
Now we know that;
Joe put chocolate icing on every 8 cookie.
Number of cookies which have Chocolate icing = {8 , 16, 24, 32, 40, 48}
Gina put sprinkles in every 5 cookie.
Number of cookies which have sprinkles ={5,10,15,20,25,30,35,40,45}
From above we can see that;
number of cookies which will have both icing and sprinkles = {40}
Hence There will be only 1 cookie (40th one) which contains both icing and sprinkles.
