Write an equation to model growth or decay in the following scenario. A stock is declining at a rate of 25% of its value every 2
yawa3891 [41]

The exponential function that models this situation is:

y(t) = 225(0.75)^{\frac{t}{2}}

------------------------------------------

A decaying exponential function has the following format:

y(t) = y(0)(1 - r)^t

In which:

  • y(0) is the initial value.
  • r is the decay rate, as a decimal.

In this problem:

  • The stock started at $225, thus y(0) = 225.
  • Declines at a rate of 25% every 2 weeks, thus r = 0.25, t = \frac{t}{2}

The equation is:

y(t) = y(0)(1 - r)^t

y(t) = 225(1 - 0.25)^{\frac{t}{2}}

y(t) = 225(0.75)^{\frac{t}{2}}

Find two numbers the quotient is between. Then estimate the quotient 284 divided by 5
Pavel [41]
The quotient is 284 divided by 5, or

284
-----         If you mult. numerator and denominator by 2, you get 578/10, or 57.8.
   5

Try the numbers 550 and 600 (because 574 is between them).  Now divide 550 and 600 by 10; the results will be 55 and 60.  The actual value of 284/5 is between 55 and 60:  57.8 (which you can verify with a calculator).
