Moon exponential growth
Name_______________________________
Imagine that you had a sheet of paper big enough to fold in half 50 times. Of course
that would be impossible, but let’s pretend that you did.
Do you think that after 50 folds the paper would be think enough to reach from here to
the moon? The moon is about 240,000 miles (15,000,000,000 inches) from Earth.
Complete the table below for the first 10 folds.

After 10 folds the paper is approximately ____________ inches thick.
Determine the thickness after:
20 folds _________________________ inches
30 folds _________________________ inches
40 folds _________________________ inches
50 folds _________________________ inches
What equation could you use to determine the thickness after x number of folds?
