Ответ:
c. $ 620
Step-by-step explanation:
Given,
Number of friends = 3,
Rent of apartment for a month = $ 650,
So, the total rent for 2 months ( First and last ) = 2 × 650 = $ 1300
Let x be the amount of security they paid,
⇒ Total money paid by them = 1300 + x,
According to the question,
They each paid $ 640,
⇒ Total money paid by them = 3 × 640 = $ 1920
⇒ 1300 + x = 1920
⇒ x = 1920 - 1300 = 620,
Hence, the amount of security deposit was $ 620.
