Answer:
part A) 
par B) 
Step-by-step explanation:
Part A)
Let
p ----> the number of pounds of cake
f ----> the number of cups of flour
we know that
A relationship between two variables, p, and f, represent a proportional variation if it can be expressed in the form
or 
Find the value of k
For p=3, f=8.25 ---->
therefore
The linear equation is

Part B) we have
For p=14
substitute in the equation and solve for f

Take 1/2 of 1 and square it and add to both sides
1/2 squared=1/4, add to both sides
x^2+x+1/4=19/4+1/4
factor perfect square
(x+1/2)^2=20/4
(x+1/2)^2=5
square root both sides
x+1/2=+/-√5
minus 1/2 both sides
x=-1/2+/-√5
x=-1/2+√5 or
x=-1/2-√5
B is answer
