Muffins cost $3.00 per dozen.
GenaCL600 [577]

Answer:

I agree with both of them

Step-by-step explanation:

A dozen is 12 muffins. Therefore, you pay $3.00 for 12 muffins.

We know that you pay $3.00 for 12 muffins we need to find out how much EACH muffin cost. For that we need to divide $3.00 by 12 which is 0.25.

Now we need to know how much it will cost us for 16 muffins. We use our equation 16*0.25 which is 4. Elena said she will pay 4 so she is right.

Andre said he will buy 8 muffins so we use our equation again 8*0.25 which is 2. He said he will pay 2 so he is right.

f( -  \frac{b}{2a} )

When you not given the vertex form, the you are given the standard form:

f(x) = a {x}^{2}  + bx + c

The value of k, is the y-value of the vertex of the function.

To find the value of k, you plug in

x =  -  \frac{b}{2a}

In order works, you evaluate

f( -  \frac{b}{2a} )

This will give you the k-value
