Katya sold 8 glasses of lemonade and Ricky sold 9 glasses of lemonade. If Tina sold twice as many as Katya and Ricky's combined sales, how many more glasses of lemonade than Katya did Tina sell?

How many glasses of lemonade did Katya and Ricky sell? ** Katya and Ricky sold 8 + 9 = <<8+9=17>>17 glasses of lemonade.
How many glasses of lemonade did Tina sell? ** Tina sold 17 x 2 = <<17*2=34>>34 glasses of lemonade.
How many more glasses of lemonade than Katya did Tina sell? ** Tina sold 34 - 8 = <<34-8=26>>26 more glasses of lemonade than Katya
