Part A. Markdown answer = $233.93
$259.92*0.10=$25.992 or $25.99
$259.92 - $25.99 = $233.93 cost after 10% markdown
Part B. Markup answer = $337.90
$259.92 * 0.30= $77.976 of $77.98
$259.92 + $77.98 = $337.90 cost after 30% markup
C I’m pretty sure, if wrong I’m sorry
Y=3x-5
y-3x=-5
Times 2 from both side
y(2)-3x(2)=-5(2)
2y-6x=-10
Times negative from both side
(-)2y-6x(-)=(-)-10
-2y+6x=10
or
6x-2y=10
6x=2y+10
6x-2y=10
Furthermore, we see that both equation have the same 6x-2y=10 which means that both of them have infinity solutions, not a solution. Hope it help!
Answer:
0.5 or 1/2
Step-by-step explanation: Use the slope formula: y2 - y1 / x2 - x1
0 - (-2) / -5 - (-9)
