13. Your parents would like to help you purchase your first home. They know you will need
$19,351.43 for a down payment in 10 years. They

A) $100.00
C) $2,015.86
B) $245.14
D) $145.48

Not the second one, I believe it’s the last one

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
