If the value of land in an area is increasing 8.5 percent a year, how long will it take for property values to double?

The formula y= a(1.085^t) can be used to determine the value of the property (y) after a given number of years (t), based on an initial value (a). Since the valueis to double, substituting 2a for y gives us 2a = a(1.085^t), for which the a's cancel. Taking the natural log of both sides gives ln(2)=t ln(1.085). Solving for t gives approximately 8.5 years.

Do the math. she originally had 50 dollars on her gift card and she had 12 dollars left on her gift card after she finished her shopping spree. if you subtract 50 minus 12 you get thirty eight dollars as your answer. so therefore, ciara spent 38 dollars total o
