let's firstly convert the mixed fraction to improper fraction.
[tex]\bf \stackrel{mixed}{1\frac{3}{4}}\implies \cfrac{1\cdot 4+3}{4}\implies \stackrel{improper}{\cfrac{7}{4}}\impliedby \textit{for each day} \\\\\\ \stackrel{day~one}{\cfrac{7}{4}}+\stackrel{day~two}{\cfrac{7}{4}}+\stackrel{day~three}{\cfrac{7}{4}}+\stackrel{day~four}{\cfrac{7}{4}}\implies \stackrel{\stackrel{Lakeisha}{\downarrow }}{\cfrac{28}{4}}\implies \stackrel{\stackrel{Glenda}{\downarrow }}{7}[/tex]
so, they are both correct.
