Answer 2

Didn't you just ask this?

PROBLEM 1:
She earns 4% simple interest each year. That's 32% after 8 years.

Let x be the starting amount. The interest is computed as:
0.32x = $1536

Divide both sides by 0.32:
x = 1536/0.32
x = 4800

Double-check.
4800 x 0.04 = $192 per year
8 years x $192 = $1536

Answer:
Hannah started with $4800.

PROBLEM 2:
The price goes down by 3.50 (28 - 24.50). Compute this as a percent of the original price:

3.5 / 28 = 0.125

Turn that into a percent by moving the decimal two places to the right (multiply by 100%):

Answer:
The stock suffered a 12.5% decrease (or write it as -12.5%)

PROBLEM 3:
You made $550 interest from a $5000 investment.
550 / 5000 = 0.11

Turn it into a percent by moving the decimal two places.

Answer:
11% simple interest
