Question

Select the better deal :ten donuts for $2 OR two dozen donuts for $6

Answer 1

To find out, calculate the cost of just one donut in each of the offers. So,

*If you buy ten donuts for $2, each donut costs

$\frac{\text{ \ 2}}{10}=\text{ \ 0.2}\Rightarrow\text{ cost of a donut}$

*If you buy two dozen donuts for $6​, each donut costs

$\begin{gathered} \text{ A dozen is 12 units} \\ \frac{\text{ \ 6}}{24}=\text{ \ 0.25}\Rightarrow\text{ cost of a donut} \end{gathered}$

Therefore, the better deal is ten donuts for $2, because with that offer it was cheaper to buy donuts..
