Answer: The correct option is C.
Explanation:
It is given that Micheal's savings can be modeled by the regression equation,
[tex]y=10x^2+50x+300[/tex]
Where x is the number of months and y is the amount of saving.
We have to find the best prediction for the amount he will have saved after 20 months.
Put x=20 in the given equation.
[tex]y=10(20)^2+50(20)+300[/tex]
[tex]y=10(400)+1000+300[/tex]
[tex]y=4000+1000+300[/tex]
[tex]y=5300[/tex]
He can save 5,300 after 20 months.
Therefore the correct option is C.
