### Instruction:
A watermelon stand sold 46 watermelons. Seventeen customers bought one melon, three customers bought three melons, and the rest bought two melons. How many customers bought two watermelons?

### Response:
 Wateja walionunua tikiti moja walikununua 1 * 17 = <<1*17=17>>17 tikiti.
Wateja walionunua tikiti tatu walikununua 3 * 3 = <<3*3=9>>9 tikiti.
Kibanda kiliuza tikiti 46 - 17 - 9 = <<46-17-9=20>>20 kwa wateja walionunua tikiti mbili.
Kulikuwa na wateja 20 / 2 = <<20/2=10>>10 walionunua tikiti mbili.
