Randee invested $1000 for college in an account earning 5% simple interest. When she withdrew the investment, she had earned a total of $550 in interest. How long was the money invested?

So you first need to find what 5% of $1000 is. You can do that by multiplying $1000 by .05. You would get X. $550/X= your answer.

So it's C? 11 yrs? Anyways thanks Janey :3

Time = Interest/(principal x rate)

= 550/(1000(.05) = 550/50 = 11
yup, its 11

YES!

To find out how long the money was invested, we can use the formula for simple interest:

Interest = Principal × Rate × Time

We have the following information:

Principal = $1000
Rate = 5% (or 0.05)
Interest = $550

We can rearrange the formula to solve for time:

Time = Interest / (Principal × Rate)

Plugging in the given values, we have:

Time = $550 / ($1000 × 0.05)
= $550 / $50
= 11 years

Therefore, the money was invested for 11 years. The answer is option C: 11 years.
