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?

Answer 1

Answer: $1,624

Explanation:

The amount after x-years is given as :

9
`x^(2)` + 50x + 1000

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

9(
`6^(2)` ) + 50(6) + 1000

⇒9(36) + 300 + 1000

⇒324 + 300 + 1000 =

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