You are giving the following amounts: $190,258.50; $152,698.00; $122,753.00; $220,523.00; $231,951.00. what is the average of these five amounts?

This is a really simple problem once you understand how to solve it, and that's what I'm going to show you! :)

When calculating the mean (average) of multiple numbers, your first step is to add the numbers together.
190,258.50 + 152,698.00 + 122,753.00 + 220,523.00 + 231,951.00 = 918,183.50

Then you take the sum of your numbers, and divide the sum by the amount of numbers added, which in your case, is 5.

918,183.50/5 = 183,636.70

The average of these numbers is $183,636.70

(x+2)(1-x)=-4

subtract 2 from both sides: x(1-x)=2

simplify:x-2x=2

subtract: -x=2

switch the negatives

x=-2
