First, add together the costs for buying their own stuff. 250+135+69+25=479.
Then figure for the professional costs. Put it in perspective of a year. 45*11+75=570.
Then subtract. Professional- DIY. 570-479=91.
$91 is about 2 months worth of work. So a year has 12 months.
12-2=10
Answer:10 months
X² +4x+y²-2y=20
x²+2*2x+4 +y²-2y+1 =20+4+1
(x+2)²+(y-1)²= 25
(x+2)²+(y-1)²= 5²
