[tex]\bf \begin{array}{ccll} lbs&days\\ \text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\ 70&80\\ 87.5&d \end{array}\implies \cfrac{70}{87.5}=\cfrac{80}{d}\implies d=\cfrac{87.5\cdot 80}{70}[/tex]

80/70=8days/7pounds
Convert 87.5 pounds to days.
87.5 pounds*(8days/7pounds)=100 days 
*As you can see, in the second equation, pounds cancel out, leaving just days
