3/8 = 9 blueberry muffins so 15 (or 5/8) of the muffins should be strawberry if that's the only other kind of muffins in this equation.
Answer:

Step-by-step explanation:
Let x be the distance driven, d-distance and C our constant.
Our information can be presented as:

#Subtracting equation 2 from 1:

Hence the fixed cost per mile driven,
is $0.20
To find the constant,
we substitute
in any of the equations:

Now, substituting our values in the linear equation:
#y=cost of driving, x=distance driven
Hence the linear equation for the cost of driving is y+0.2x+284

Answer:
Step-by-step explanation:
r=4/(-2)=-2
For #6;
We know that there are 46% male students and 30% of them are seniors. This means that we have to assume that 30% of the male students are seniors and that 30% of the female students are seniors. Taking 30% of 46% gives us 13.8%.
For #7;
We are looking for the possibility that we choose a junior student (22%) or a sophomore student (28%). This adds up to 50% (22%+28% = 50%). That is out answer.
