Answer: I would figure it would be 10
Step-by-step explanation: if the total value is $70 at the beginning and it constantly loses 15 each month for 4 months that would mean it would lose $60 by the end of the 4 months minus that value from 70 and you get 10.
Answer:
73
Step-by-step explanation:
Mean is the number of copiers combined / number of months
79 * 5 = 395
93 + 30 + 138 + 61 = 322
395 - 322 = 73
