Question

Mr. Simpson feeds his dog a 1/2 cup of dog food each day. How long will a 26 cups of dog food last?

Answer 1

The cup of food required for a day, N=1/2 cup.

Total number of cups, T=26.

The number days 26 cups of food will last is,

$\begin{gathered} n=\frac{T}{N} \\ n=\frac{26}{\frac{1}{2}} \\ n=26\times2=52 \end{gathered}$

Therefore, 26 cups of food will last for 52 days.
