1) Free Time
Lindsey saw this ad in a computer magazine.
Come INTER-the-NET with us.
FREE 10-DAY Trial!
Get 1 minute of free time the first day, 2 minutes of free time the
second day, 4 minutes of free time the third day, 8 minutes of free
time the fourth day, 16 minutes on the fifth day, and so on.
�What good is 1 minute, 2 minutes, or even 4 minutes of time
online?� Lindsey wondered. �I would need a lot more time than that
to find out how good this service could be!�
If Lindsey signed up for the 10-day trial of Internet service, how
many minutes of free time would she get on the 10th day?
HINT: Look for a pattern in the numbers of free minutes.

2) Software Selections
Morgan, Faith, Noah, and Brady have each purchased one
piece of software at a software store. Each person chose software
based on what he or she wants to be when he or she grows up. One of
them bought sports software, one bought flight-simulation software,
one bought digital photography software, and one bought music-
creation software.
Faith and Noah watched the one who bought the sports software
play baseball.
Brady and Morgan aren't interested in photography.
Faith wants to be a pilot when she grows up.
One of the boys wants to be a musician when he grows up.
Who bought each type of software?
HINT: Make a chart and eliminate the impossibilities.
