Question

Over two summers, Ray saved $900 and $500. The polynomial 900x2 + 500x represents his savings at the beginning of the third year, where x is the growth factor. (The interest rate r is x - 1.) What is the interest rate he needs to start the third year with $1600 in savings?

A. 1.1%
B. 0.1%
C. 8.4%
D. 264%

Answer 1

Polynomial=900x^2+500x represents his saving at the beginning of the third year.
Interest rate r= x-1
"interest rate he needs to start the third year with $1600 in savings"
