Question 1188925
.
Ben earns 20c for every card he sells. When he sells a whole box of 12 cards he earns an extra $2. 
How many cards does he need to sell to earn $332.
~~~~~~~~~~~~~~


<pre>
According to the problem, Ben earns 12*20 cents PLUS 2 dollars = 4.40 dollars for every box of 12 cards sold.


So we divide  $332  by  $4.40  to get  {{{332/4.40}}} = 75.4545...


We round this value to the closest integer number, which is less than 75.4545..


This value is 75, which means that Ben should sell 75 boxes.


He will earn then  $4.40*75 = $330.


So, Ben should sell 75 boxes of 12 cards each  PLUS  10 additional separate cards.


The total number of card sold is then  75*12 + 10 = 910.     <U>ANSWER</U>
