Sliva [168]

Answer:

Step-by-step explanation:

steps are below

step 1

y^3-8y^2+19y=12 equation

step 2

y^3-8y2+19y(-12)=12(-12) minus 12 from both sides

y^3-8y^2+19y-12=0

step 3

(y-1)(y-3)(y-4)=0 add brackets

step 4

(y-1)(y-3)(y-4)=0 factor

step 5

y-1=0 or y−3=0 or y-4=0 set them equal

Answer:

y=1 or y=3 or y=4

1. B. The retail price would be the purchase price plus the markup.
So p+.40p = 1.40 p = 1.4 p. (p is really 1 p)
C. You would multiply: 1.4(56) = $78,40
D. You could multiply .4p = .4(56). OR subtract: 78.40-56 = $22.40

2. Done
3. 10(.35) = $3.50 —— 10+3.50=$13.50
4. 40(.25) = $10 ———- 40+10=$50
5 Done
6. $30.50/30% markdown 30.50(.30) = $9.15; 30.50-9.15= $21.35
7. $105/75% markdown 105(.75) = 78.75; 105-78.75= $26.25
8. $325/15% markdown 325(.15) = 48.75; 325-48.75= $276.25
9. C/40%markup Total retail:.40c + c = 1.40C
