Question

Pencils are 3 for $0.35. How much would 2 dozen pencils cost?

Answer 1

We have that 3 pencils cost $0.35, and 2 dozen pencils are 24 pencils, then we divide by 3 to know how many 3-pencils combo we can get:

$\begin{gathered} \frac{24}{3}=8 \\ \Rightarrow8\cdot(0.35)=2.8 \end{gathered}$

therefore, 2 dozen pencils would cost $2.8
