7 in the expression above represents a factor because after adding 3 and 13, you would need to multiply 2 and 5. Then, you will multiply 7 and 16 which shows that 7 in the expression above represents a factor.

Herbert has sold 90, 45, 103 and 68 appliances in the last four months, respectively. How many appliances will he need to sell t

Elena-2011 [213]

Answer:

The sale this month = 79

Step-by-step explanation:

Let the amount he needs to sell this month = x

$Average = \frac{sum\ of\ individual\ data\ }{number\ of\ entries}$

$Average= \frac{90\ +\ 45\ +\ 103\ +\ 68\ +\ x}{5}$

Note that number of entries = number of months = 5

To maintain an average sales of 77, the amount of sale in month 5 is determined as follows:

$77 = \frac{306\ +\ x}{5} \\cross-multiplying\\77\ \times\ 5\ = 306\ +\ x\\385 = 306\ +\ x\\x =385\ -\ 306\\x = 79$
