DJ Bronson is making a playlist for a demo CD; he is trying to decide what 10 songs to play and in what order they should be played. Step 2 of 2 : If he has his choices narrowed down to 7 blues, 6 rock, 4 country, and 6 jazz songs, and he wants to play all 7 blues songs, how many different playlists are possible? Express your answer in scientific notation rounding to the hundredths place.

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)
