Answer:

Option D

Step-by-step explanation:

The equation to predict the amount saved is

$y = 6x ^ 2 + 75x + 200.$

Assuming that the variable x represents the saving months, then substitute $x = 25$ in the quadratic equation and solve for y.

$y = 6 (25) ^ 2 +75 (25) +200\\\\y = \$\ 5,825$

The answer is the option D $5,825
