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

### Instruction:
Adrian has the choice between two boxes of contacts.  One has 50 contacts for $25, and the other has 99 contacts for $33. He chooses the box that costs less per individual contact.  How many contacts will it take to equal $1 worth in whatever box he decides to buy?

### Response:
 Kwanza, tunahitaji kujua gharama ya kila mawasiliano katika kila chaguo. Tunanza kwa kufanya 50/25 = <<50/25=2>>2 mawasiliano kwa kila dola iliyotumika kwenye chaguo A.
Kisha, tunahesabu gharama ya kila mawasiliano ya chaguo B kwa kufanya 99/33 = <<99/33=3>>3 mawasiliano kwa kila dola iliyotumika kwenye chaguo B.
Kwa kuwa 3>2, Adrian anachagua chaguo B.
Ili kujua mawasiliano mangapi yanahitajika sawa na $1, tunazidisha 1*3 = <<3=3>>3.
