How many boxes did Robie fill? ** Robie filled a total of 2 + 5 = <<2+5=7>>7 boxes.
How many cards did Robie have in the beginning? ** So, he had 7 x 10 = <<7*10=70>>70 hockey cards from the 7 boxes.
How many cards did Robie have in the beginning? ** Thus, he had a total of 70 + 5 = <<70+5=75>>75 cards in the beginning.
