<span>x + 3y = –9
3x – 3y = 21
-------------------add
4x = 12
x = 3
substitute x = 3 into </span>x + 3y = –9
3 + 3y = –9
3y = -12
y = -4
Answer
(3, -4) is the solution of the system.
Since he sold it for $75 more,
% Mark Up = Mark Up/ Cost Price x 100%
% Mark Up = 75 / 125 x 100% = 0.6 x 100% = 60%
Percent Mark Up = 60%
Hope this helps :)
Answer:
Step-by-step explanation:
y = 0.2x + 17......the slope is 0.2 (or 1/5)....in y = mx + b form, the slope can be found in the m position
(x,18).....y = 18 (25,y).....x = 25
y = 0.2x + 17 y = 0.2x + 17
18 = 0.2x + 17 y = 0.2(25) + 17
18 - 17 = 0.2x y = 5 + 17
1 = 0.2x y = 22..........(25,22)
1 / 0.2 = x
5 = x.................(5,18)
