The answer is C
x= months
y=$
Constant of proportionality (C)=y/x
x=1, y=3.5
3.5/1=3.5
x=2, y=7
7/2=3.5
x=3, y=10.5
10.5/3=3.5
x=4, y=14
14/3=3.5
x=5, y=17.5
17.5/5=3.5
C=3.5

Answer:

No real

solution

Step-by-step explanation:

Firstly, let us check if we would be having a real solution

We start by rewriting the equation

We have this as;

8x^2 -25x + 24 = 0

We proceed to get the discriminant

Mathematically, we have this as;

D = b^2 - 4ac

b is the coefficient of x which is -25

a is the coefficient of x^2 which is 8

c is the last number which is 24

So we have;

D = (-25)^2 - 4(8)(24)

D = 625 - 768 = -143

Since the value of the discriminant is negative, there cannot be real roots

What we have as solution are complex roots
