Question: Tonya has opened a lemonade stand selling lemonade in small, medium, and large cups at $1, $2 and $3 respectively. At the close of business she ended up making $50.  As she went back through her inventory she noticed that she sold $11 worth of small lemonades and $24 worth of medium lemonades. How many cups of large lemonade did Tonya sell? Is final answer 5?
Answer: 1. Tonya sold $11 worth of small lemonades and $24 worth of medium lemonades which makes $11 + $24= $<<11+24=35>>35 for small and medium lemonades.
2. Tonya made a total of $50. If she made $35 selling the two smaller sizes and she sold three sizes in all then $50-$35= $<<50-35=15>>15 worth of large lemonades.
3. The large lemonades sold for $3 each and Tonya sold $15 worth of large lemonades which means she sold $15/$3=<<15/3=5>>5 large cups of lemonade.
