Question

In a cookie mix, we find oatmeal cookies,

Answer 1

Answer:

100 : 20 : 60 Making the total number of cookies 180

Step-by-step explanation:

Looking at the basic information given we know:

If there are 5 oatmeal cookies, there will be: 1 raisin cookie and 3 butter cookies. This is a base value.

So, we have equations like this:

$r = 1/3b$ and $o = 5/3b$

So, if we plug in 60 for butter cookies we will have something like this:

$o : r : 60$ or $(5/3b) : (1/3b) : b$ where b=60

Solving:

$(5/3b) : (1/3b) : b$

$(5/3b) : (1/3b) : 60\\100 : 20 : 60$

Then add the amounts of together to get 180.

I hope this helps! It's a bit difficult to explain, where I do most of this in my head, but I hope this will be able to provide some understanding to you.
