Question

I have 9 cowry shells. If a dozen eggs (12 eggs) cost 2 cowry shells, how many dozens can I purchase?

A.3 dozen

B.4 dozen

C.6 dozen

D.11 dozen

Answer 1

Answer:

B. 4 doz  

Explanation:

$\text{Amount of eggs}= \text{9 cowry shells} \times \dfrac{\text{1 doz eggs}}{\text{2 cowry shells}} = \text{ 4.5 doz eggs}$

"They" won't let you buy a fraction of a dozen, so you can afford to buy only 4 doz eggs.
