So totally confused please help

Answer 1

Answer:

The answer to your question is: r = 0.1

Step-by-step explanation:

Data

P = $4500

A = $9000

t = 9 years

r = rate

Formula

                            $r = \sqrt[t]{\frac{A}{P}} - 1$

Substitution

                             $r = \sqrt[9]{\frac{9000}{4500} - 1$

Simplification

                             $r = \sqrt[9]{2} - 1$

Result

                             r = 1.08 - 1

                             r = 0.08 ≈ 0.1
