Answer:
C) 800%
Step-by-step explanation:
The markup amount is the difference between the selling price and the cost:
markup = selling price - cost
markup = $63 -7 = $56
The percentage markup relative to the cost is ...
markup/cost × 100%
= ($56)/($7) × 100%
= 8×100% = 800%
Answer:
(-3, 0)
(0, 3)
(1, 4)
Step-by-step explanation:
It’s easier if you make an equation like this!
Start by finding the slope using two points
m = slope
m = y2 - y1/x2 - x1
For right now, I’m going to have to use two points from the graph.
Points: (-5, -2) and (0, 3)
m = 3 - -2/0 - -5
m = 5/5
m = 1
Now find the y-intercept (located where x coordinate is 0)
y-intercept = 3
Now make the equation of a line that has a slope of 1 and a y-intercept of 3
y = x + 3
Now use any point to see if it is a point on the graph.
y = x + 3
Point: (2, 5)
5 = 2 + 3
5 = 5
Therefore it is a point
y = x + 3
Point: (-3, 0)
0 = -3 + 3
0 = 0
y = x + 3
Point: (2, 4)
4 = 2 + 3
4 = 5
Answer: Option D
Explanation:
x = input
y = f(x) = output
Table D shows the input x = 2 pair up with the output y = f(x) = 0. But this curve does <u>not</u> cross the x axis. So we can conclude that table D is an incorrect model to represent this curve.
Answer:
17/16= 1.06 (rounded)
16/17= 0.94 (rounded)
9/45= 0.2
5/13= 0.38 (rounded)
-28/35= -0.8
15/20= 0.75
