Answer:
D. p is multiplied by 2
Step-by-step explanation:
43. We can simplify the formula a bit to better see the effect of changing 'a'.
[tex]p=\dfrac{\dfrac{1}{2}ary+a}{12y}=\dfrac{ary+2a}{2(12y)}=\dfrac{a(ry+2)}{24y}[/tex]
This tells you that for unchanging values of r and y, the value of p is proportional to the value of a. That is, the formula is of the form ...
p = ka . . . . for k=(ry+2)/(24y)
If a is multiplied by 2, p is multiplied by 2.
