Question

Shaun's savings can be modeled by the regression equation y = 6x^2 + 75x+200. Which of the following is the best prediction for the amount he will have saved after 25 months?

A. $3,791
B. $3,754
C. $2,936
D. $5,825

Answer 1

Option D

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
