A because my computer hates me is one sentence and I really think it does is another sentence so you can't have 2 sentences in one
I believe the colons should be placed as follows:
1. One thought kept crossing Jen's mind as Friday approached:
2. included the following: life, liberty, and the pursuit of happiness
3. cultures:
on the first sentence you are separating her thought from the statement
on the second, you are separating a list from the statement
on the third, you are separating the two different types of cultures from the statement.
I really hope these are correct for you :) good luck!
Robin will need 20 pages of 10 stickers each. Dividing up the 180 stickers she already has into equal amounts of ten on individual pages, will add her up to 18 pages of stickers. She will need 20 more stickers to accumulate a total of 200: aka: 20 pages of stickers filled with ten each.
