Question

Wilbur has sold 93, 42, 101 and 72 suits in the last

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

Answer 1

To maintain an average of at least 77 sales per month over the five months (including the current month), Wilbur needs to ensure that the total sales for these five months add up to at least (5 times 77 = 385) suits (since the average is calculated by dividing the total by the number of months).

Now, let's calculate the total number of suits he has sold in the last four months:

[93 + 42 + 101 + 72 = 308]

To reach a total of at least 385 suits for the five months, he needs to sell:

[385 - 308 = 77] suits this month.

So, Wilbur needs to sell at least 77 suits this month to maintain an average of at least 77 sales per month over the five months.
