Answer:
x^2 - 2xy + y^2.
Step-by-step explanation:
(x - y)^2
= (x - y)(x - y)
= x(x -y) - y(x - y)
= x^2 - xy - xy + y^2
= x^2 - 2xy + y^2.
So first you’ll have to find the total or the sum of collected.
$90+$60= $150
Because you’re finding the percent of the total collected by girl scouts, divide the amount collected from the girl scouts by the total.
$90/$150= .6
Multiply that by 100 to get %60.
