Arianna is saving money for college so she invests $1,000 into a savings account that earns interest every year. If the amount in the savings account is represented by the function
9x2+50x+1000, where x is the number of years. How much money does Arianna have in her account after 6 years?

Respuesta :

Answer: $1,624

Step-by-step explanation:

The amount after x-years is given as :

9[tex]x^{2}[/tex] + 50x + 1000

Since x represents number of years , this means that after 6 years , the amount will be :

9([tex]6^{2}[/tex] ) + 50(6) + 1000

⇒9(36) + 300 + 1000

⇒324 + 300 + 1000 =

Therefore, the amount after 6 years will be $1,624
