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 7/6 as much as the small cups, what fraction of Tuesday's total revenue was from the sale of large cups?

IMO A
plugging in numbers:
total lemonade sold=100
small=60
large=40
price of small cup=6
total from small cups=60*6=360
price of large cups=7
total from large cups=280
280/(280+360)= 7/16
plugging in numbers:
total lemonade sold=100
small=60
large=40
price of small cup=6
total from small cups=60*6=360
price of large cups=7
total from large cups=280
280/(280+360)= 7/16
The powers of two are bloody impolite!!
