Step-by-step explanation:
3. Slope is postive
x1=6
x2=3
y1=10
y2=6
m=6-10/3-6
m=4/3
y=mx+b find b
10=4/3*3+b
10=4+b
b=6
y=4/3x+b
4.slope is zero
y=b
Y=3
The number of ways for arranging is n!
Total sample = 30+20+18
= 68
Number of ways to arrange
= 68!
= 2.480035542437 x 10^96
Answer=$3.20
8%=0.08
$40.00*0.08=$3.20
The markup was $3.20
