Question 1195083
.
A baker needs 4 eggs to make a cake and 6 eggs to make a flan. 
The baker purchases eggs in cartons of 12. 
If the baker wants to make 8 cakes and 6 flans, 
what is the minimum number of cartons the baker must purchase?
~~~~~~~~~~~~~~~~~~


<pre>
The number of eggs needed to make 8 cakes and 6 flans is 8*4 + 6*6 = 32 + 36 = 68.


So, 5 cartons of eggs (giving 60 eggs) is not enough; let's try 6 cartons.


6 cartoons carry 6*12 = 72 eggs.


It is just enough for the baker needs, since 72 > 68.


<U>ANSWER</U>.  5 cartoons are not enough, but 6 cartoons is just enough: 

         so, 6 cartoons is the minimum number of cartoons to buy.
