Just add the numbers in without the dollar sign in front. Have one axis as money and the other as amount then add in the data.
A + B + C = 180
<span>C = 180 - A - B </span>
The mathematical property that allows 40 * (25 * 74) = (40 * 25) * 74 would be the Associative Property of Addition and Multiplication. This property means that no matter how the values of an expression are grouped together (or "associating" with each other), the end result will be the same, as long as the symbols are all either multiplication or addition symbols.
Hope that helped =)
So since 4 was added to x then 2 subtracted from y, to reverse it
minus 4 from x and add 2 to y
(x,y)
(5,-3)
minus 4 and add 2
(1,-1) is the reverse translated
answer is last one
