Which of the following represents 12% growth per time period?
f(x)= 1,000 x 1.12x
g(x) = 1,000 x 0.12x
h(x) = 1,000 x 0.8x
k(x) = 1,000 x 88x

f(x) = 1,000(1.12)x

Step-by-step explanation:

You can use your context clues to figure out this answer.

Your goal is to find an answer that :

1) The number is greater than 1,000 (since it grows)

2) The number doesn't increase too much, but a close estimate to 12%

A percentage (that is less than 100%) is a decimal number. A percentage represents that number out of 100. So, 12% is only 12 out of 100.

Meaning that .12 = 12%. But in this case, we want an increase of 12%. Since we want it to grow from our initial value, 1,000, you want to find where the multiplier is greater than 1. Because 100% of 1000 is 1000. + .12 = 112%.

If you put in your calculator, 1000 * 1.12, you should get 1,120

. g(x) actually decreases 1,000. It actually gets 12% of 1,000.

h(x) represents 80% of 1,000 but not an increase of 12%.

k(x) is such a huge number and should automatically be negated/crossed off.
