y=2.5x .

Step-by-step explanation:

Let x represent the number of cupcakes and y represent total cost.

We know that two proportional quantities are in form y=kx , where, k represents constant of proportionality.

1 dozen = 12

Half dozen = 6

Let us substitute y=15 and x=6 in above equation.

15=k*6

$\frac{15}{6}=\frac{k*6}{6}$

$\frac{5}{2}=k$

2.5=k

Therefore, the constant of proportionality is 2.5 and our required equation would be y=2.5x .

$2x^{3}+x^{2} -4x+3\\remainder: 14$

Step-by-step explanation:

My work is attached. I used long and synthetic division because I wasn't sure which you were familiar with.
