1. Cynthia rounds the number, which is identified as , to one decimal place and the result is 6.3.
2. Based on this, we know that could have been between 6.25 and 6.35. Therefore, the error interval for
is given by:
Where indicates that the value 6.25 is included and
indicates that the value 6.35 is not included (Because if

for the second condition , i.e, she wants to purchase at least 12 books,
the required inequality will be:
2). the graph is in the attachment..
3). x,y are the two required solutions. where,
x =number of paperback books she buys.
