Question

The table shows the weekly profits of a fruit vendor. What is the mean profit for these weeks?

Week	1	2	3	4
Profit	$-\$125$	$-\$86$	$\$54$	$-\$35$

Answer 1

We know that Mean profit $=\frac{sumofprofit}{numberofweeks}$

So, Mean profit $=\frac{(-125)+(-86)+54+(-35)}{4}$

$$\begin{gathered} =\frac{-125-86+54-35}{4} \\ =\frac{-246+54}{4} \\ =\frac{-192}{4}=-48 \end{gathered}$$

The mean profit for 4 weeks is $-\$48$.

Hence, The mean profit for 4 weeks is $-\$48$.
