If a is a negative number and b is a negative number, which expression is always negative?

a + b

Step-by-step explanation:

if a = -1, and b = -5

-1 + -5 = -6

(a) negative times (b)negative = positive

(a)negative times (b)positive = negative

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.
