### Instruction:
 Mwaka jana Dallas alikuwa mara tatu umri wa dada yake Darcy. Darcy ni mara mbili umri wa Dexter ambaye ana miaka 8 sasa. Dallas ana umri gani sasa?


### Response:
 Darcy = 2*Dexter = 2*8 = <<2*8=16>>16
Mwaka jana Darcy alikuwa na miaka 16 - 1 = <<16-1=15>>15
Dallas alikuwa mara tatu ya Darcy mwaka jana = 3 * 15 = <<3*15=45>>45
Dallas ni mwaka mmoja mkubwa sasa = 45 + 1 = <<45+1=46>>46
Dallas ana miaka 46 sasa.
