Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
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?

### Response:
 Robie alijaza jumla ya masanduku 2 + 5 = <<2+5=7>>7.
Hivyo, alikuwa na kadi 10 x 7 = <<10*7=70>>70 za hockey kutoka kwenye masanduku 7.
Hivyo, alikuwa na jumla ya kadi 70 + 5 = <<70+5=75>>75 mwanzoni.
