If it has been marked up 40% then you now have 140%. To find 140% of $63 you need to multiply 63 by 1.4 to give $88.20. So the mark up is $25.20
Set each set of parentheses to 0 and solve for the x’s
X-1= 0
Add 1 to both sides
X =1
X-7 = 0
Add 7 to both sides
X = 7
The zeros are 1,7
To plot them make dots at (1,0) and (7,0)
