 Elijah alikunywa pinti 8.5 za kahawa jana. Emilio alikunywa pinti 9.5 za maji jana. Vijana hao wawili walikunywa vikombe vingapi vya kioevu jana?


### Response:
 Jumla ya vikombe vilivyokunywa: 8.5 + 9.5 = <<8.5+9.5=18>>18 pinti
18 pinti * 2 = <<18*2=36>>36 vikombe
Vijana hao wawili walikunywa jumla ya vikombe 36 vya kioevu jana.
