lys-0071 [83]
Remember, we can do anything to an equation as long as you do it to both sides

and distributive proeprty, reversed
ab+ac=a(b+c)

xm=x+z
minus x from both sides
xm-x=z
xm-1x
undistribute x
x(m-1)=z
divide both sides by (m-1)
x=\frac{z}{m-1}

Jlenok [28]

Answer:

$0.60

Step-by-step explanation:

The mean is the average. We add up all the numbers and divide by the number of numbers.

The total for 1st week is  $12.48+$9.50+$10.25+$4.99+$8.59 = $45.81

Now, the mean:

Mean = 45.81/5 = $9.162

2nd week's total is 3 more than last week's total, so 2nd week's total is:

45.81 + 3 = $48.81

Now, Mean:

Mean = 48.81/5 = $9.762

The increase is  9.762 - 9.162 = $0.60
