Charlie was reading a 134 page book on space for his
nonfiction reading project. So
far, he has read 14 pages, and
he has 10 more days to finish
the book. If it takes him 2
minutes to read a page and
he wants to read an equal
number of pages each day,
how much time will he need to
spend reading before the due
date?

Ascientist wants to use a model to present the results of his detailed scientific investigation. why would a model be useful? a )because the model makes the concepts easier to understand b) because the model is easy to put together and to use c) because the model prevents other scientists from asking questions d) because the model requires the audience to pay full attention to it i don't know what to choose because between a and d a is much more likely than d because it only wants to get the attention of the audience. i'm confuse.
