Robie filled some plastic boxes with hockey cards. There were 10 cards in each box but 5 cards were not placed in a box. He gave away 2 boxes to his friends and he has 5 boxes with him. How many cards did Robie have in the beginning?
Robie filled a total of 2 + 5 = <<2+5=7>>7 boxes.
So, he had 7 x 10 = <<7*10=70>>70 hockey cards from the 7 boxes.
Thus, he had a total of 70 + 5 = <<70+5=75>>75 cards in the beginning.
