Answer:
[tex]7\frac{1}{12}[/tex] or [tex]\frac{85}{12}[/tex]
Step-by-step explanation:
total boxes = Jills boxes + Mikes boxes
total boxes = [tex]5\frac{1}{3} +1\frac{3}{4}[/tex]
= [tex]\frac{16}{3} + \frac{7}{4}[/tex]
= [tex]\frac{64+21}{12}[/tex]
= [tex]\frac{85}{12}[/tex]
= [tex]7\frac{1}{12}[/tex]
