Yes, she has enough
From the question, we want to know if she has enough
She has 10 ounces
She needs 6 ounces for the first recipe
So what is needed for the second recipe will be (10-6) = 4 ounces
Now, she needs a quarter of a pound for this second
Since there are 16 ounces in a pound; a quarter of this will be 1/4 * 16 = 4 ounces
Adding this to the initial 6, we have a total of 10 ounces
So what she has is equal to what she needs and that means she has enough
