Use models to make predictions

Making predictions isn't an exact science. Ask any weather man. However, when the data is reliable and the model is well chosen, incredibly accurate predictions can be made. The scientist Edmond Halley was able to predict the future appearances of a comet (try to guess which one) in 1705 by recording its previous appearances and making models about the solar system.

That sounds kind of far out there, so let's tackle a more down-to-earth example. Pretend we're on our way home from the grocery store with some Girl Scout cookies—because, really, who can resist?—when a wizard offers to swap some magic beans for Thin Mints. It sounds like a good deal to us, but Mama Shmoop isn't thrilled and throws the magic beans outside, where they get eaten by a frog.

The frog starts cloning itself at an exponential rate. By midnight, there are 100 frogs, and at 2 a.m., there are 125 frogs. We now have two points, (0, 100) and (2, 125). Feeding the data into our trusty calculator shows us that the function y = 100(1.118)x models our froggy situation.

To predict how many frogs there will be by the time we wake up at 7 a.m., plug x = 7 into this equation.

y = 100(1.118)x
y = 100(1.118)7
y ≈ 218.32

Voila! Theoretically, there are 218.32 frogs hopping around on the lawn in the morning. Wait, what's 0.32 of a frog? Besides gross, that is. Rounding the predication down, we only have 218 frogs to face at 7 a.m.
