    Another business came around in 1993 and wiped out their profits so they went bankrupt and had no sales increase.

    So let's consider the exponential equation. What does it look like? \[F(t)=Ae^{rt}\] So that tells us that A is our initial amount and F(t) is our final amount. Since we don't know the amounts but we do know the percents, you can divide out A to get a fraction, which translates to your percentage!

    assuming they continue the same trend... you can PREDICT how much the sales will increase It increases by 1.5 times ... every 5 years .... IF you have a general formula for exponential function... you can plug these values in

    Using the formula above: ( i substituted \(\large c=e^r\)) \[\large F(t)= A \cdot c^t\]\[\implies \large 1.5 \cancel A= \cancel A \cdot c^5\]\[\implies \Large c=\sqrt[5]{1.5}\]

    So in 6 years ... it should increase by c^6 times : \[\Large = \left( \sqrt[5]{1.5} \right)^6=1.5^\left( 6/5 \right)\]
