Answer:Percent error=29%
Step-by-step explanation:
Percent error=(Estimated value-Actual value/ Actual value) × 100
Estimated value = amount of cookies Payton thought the mix could make = 36
Actual Value= Amount of cookies made= 28
Percent error= (36- 28)/ 28 x 100
=8/28 x 100
=0.2857 x 100
=28.57 rounded to 29%
Answer:
$65.
Step-by-step explanation:
Given:
The Store's wholesale price of a t-shirt is $50
The markup set by the store is 30%.
To find:
Calculate the retail price set by the store on the t-shirt.
Solution:
Wholesale price of a t-shirt = $50
Markup % = 30
<em>First of all we will find the markup value with the help of markup percentage and then we will simply add the wholesale price and markup value of T-shirt</em>.
Markup value of T-shirt = 
Retail price of T-shirt = Wholesale price of a t-shirt + Markup value of T-shirt
Retail price of T-shirt = $50 + $15
Retail price of T-shirt = $65
Therefore, the retail price set by the store on the t-shirt is $65.
Answer:
(14, 2).
Step-by-step explanation:
x - y = 12
y = 2
Solving this system:
Plug y = 2 into the first equation:
x - 2 = 12
x = 14.
Therefore the point of intersection is at (14, 2).
(-24)+9=-15
(-15)-9=-24
n=-15
Answer:
(2,0)
Step-by-step explanation:
For given line AB:
y-intercept = b = -2
slope = m = y₂-y₁/x₂-x₁
= -3/2-(-4) = -3/6 = -1/2
Equation of line AB:
y = (-1/2)x - 2
Finding equation of line that is parallel to line AB and passes through the point C(2,2):
Substituting the slope from line AB into the equation of the line
y = (-1/2)x + b.
Substituting the given point (-2,2) into the x and y values 2 = (-1/2)-2 + b.
Solving for b (the y-intercept)
, we get b = 1
Substitute this value for 'b' in the slope intercept form equation y = (-1/2)x + 1.
For x-intercept of the line, we let y = 0
0 = (-1/2)x + 1
x = -1(-2/1)
x = +2
So, the point on the x-axis that lies on the line that passes
through point C and is parallel to line AB is (2,0).
