SOLUTION
From the question, Tina bought
[tex]\begin{gathered} 3\frac{1}{2}\text{ pounds of turkey and } \\ 2\frac{1}{4}\text{ pounds of ch}eese \end{gathered}[/tex]
But she used only
[tex]1\frac{1}{2}\text{ pounds of ch}eese\text{ to make macaroni and ch}eese[/tex]
The amount of cheese she will have left is
[tex]\begin{gathered} 2\frac{1}{4}-1\frac{1}{2} \\ \text{changing to improper fraction we have } \\ \frac{9}{4}-\frac{3}{2} \\ =\frac{9-6}{4} \\ =\frac{3}{4} \end{gathered}[/tex]
Hence she has
[tex]\frac{3}{4}\text{ pounds of ch}eese\text{ left }[/tex]
