Guided Practice Suppose an investment of $10,000 doubles in value every 13 years. How much is the investment worth after 52 years? After 65 years?

A.
$520,000; $650,000

B.
$80,000; $100,000

C.
$160,000; $320,000

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
