Question

Herb has sold 93, 30, 138 and 61 copiers in the last

four months, respectively. How many copiers will he need
to sell this month to maintain an average of at least
79 sales per month?

Answer 1

73

Explanation:

Mean is the number of copiers combined / number of months

79 * 5 = 395

93 + 30 + 138 + 61 = 322

395 - 322 = 73
