A lemonade stand sold only small and large cups of lemonade on Tuesday. 3/5 of the cups sold were small and the rest were large. If the large cups were sold for 11/5 as much as the small cups, what fraction of Tuesday's total revenue was from the sale of large cups? Select:  A) (a) 7/16  B) (b) 7/15  C) (c) 10/21  D) (d) 22/37  E) (e) 1/2
A simpler way i guess would be to think that in total 5 cups were sold. Out of which 3 are small and 2 are large. Now let the small ones cost $5. so the large ones would cost $11.   So,   3*5=

<output>15</output>
15 and   2*11= 
<gadget id="calculator">  2*11</gadget>
<output>22</output>
22.   Total revenue was 15+22= 
<gadget id="calculator">15+22</gadget>
<output>37</output>
37   and Large cup sales as found above is 22   Therefore answer is 22/37   (d) 22/37
