What does a equal in 1/2(a-7)=33?

To find a, you need to isolate/get the variable "a" by itself in the equation:

   Multiply the inverse of 1/2, which is 2, to get rid of the fraction

a - 7 = 66      Add 7 on both sides to get "a" by itself

a - 7 + 7 = 66 + 7

a = 73

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.
