18) Write the compound inequality for all real numbers greater than 10 and all real
numbers less than 20.
A) 20 < x < 10
C) x > 10
B) x < 20
D) 10 < x < 20

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.

if i did my math right then the answer should but 108
