<human>:  Alain's mom bought 5 packs of red pens and also bought twice the amount of black pens than the red. If each pack has 5 pens, how many pens does Alain have?
<bot>: How many red pens does Alain have? ** Alain has a total of 5 x 5= <<5*5=25>>25 red pens.
How many black pens does Alain have? ** And he has a total of 5 x 2 = <<5*2=10>>10 packs of black pens.
How many black pens does Alain have? ** So, the total number of black pens he has is 10 x 5 = <<10*5=50>>50.
How many pens does Alain have? ** Therefore, the total number of pens he has is 50 + 25= <<50+25=75>>75.
