<human>:  Last year Dallas was 3 times the age of his sister Darcy. Darcy is twice as old as Dexter who is 8 right now. How old is Dallas now?
<bot>: How old is Darcy? ** Darcy = 2*Dexter = 2*8 = 16
How old was Darcy last year? ** Last year Darcy was 16 - 1 = <<16-1=15>>15
How old was Dallas last year? ** Dallas was 3 times Darcy last year = 3*15 = <<3*15=45>>45
How old is Dallas now? ** Dallas is a year older now = 45 + 1 = <<45+1=46>>46
How old is Dallas now? ** Dallas is 46 years old now.
