January:

$R_{Jan}=(208,000-200,000)/200,000=4.00\%$

February:

${l}R_{Feb1-15}=(217,000-208,000)/208,000=4.33\%\\R_{Feb16-28}=(263,000-257,000)/257,000=2.33\%\\R_{Feb1-28}=\lbrack{(1+0.0433)}\times{(1+0.0233)}\rbrack-1=6.76\%\\\;$

March:

${l}R_{Mar1-21}=(270,000-263,000)/263,000=2.66\%\\R_{Mar22-31}=(245,000-240,000)/240,000=2.08\%\\R_{Mar1-31}=\lbrack{(1+0.0266)}\times{(1+0.0208)}\rbrack-1=4.80\%$

Quarter 1:

                             $R_{QT1}=\lbrack{(1+0.0400)}\times{(1+0.0676)}\times{(1+0.0480)}\rbrack-1=16.36\%$
