18) N is between Zero and 50
The Squares we are looking at are 28 more than N
and 100 more than N
Thus, these squares differ by 72
and they are between 28 and 150
The list of Squares to look at are:
36, 49, 64, 81, 100, 121, 144
The pair that differ by 72 are 49 and 121,
so N is 21.
****************************
19) Try a VENN DIAGRAM
with the HONOR ROLL circle
overlapping the SPORTS circle.
120 in the over lap
300 in the sports
P(in Honor Roll given in Sports)
=  120/300 = 2/5





Warm up #4 problems 41 thru 50




(in #43) Notice that we are trying to find
a MULTIPLE of 101
that when ADDED to
a MULTIPLE of 19 
gives the SUM 2015.

Take a look at the MULTIPLES of 101.
Their PATTERN may help you get
 a partner that is a MULTIPLE of 19
If this question is too complicated,
then look at smaller squared arrangements:
4 dots gives ... squares
9 dots gives ... squares
etc.
