Answer: Second option is correct.
Step-by-step explanation:
Markup is the extra amount added to the cost price to arrive at the selling price.
As in retail market , cost price is always marked up by the retailers to make some profit and cover overhead expenses.
So, Markup is that amount that is added to the cost price.
Discount is also given to that amount only, to increase his goodwill.
Hence, Second option is correct.
A.
commutative property
B.
associative property
C.
distributive property
Answer
To solve this system of linear equations, we can use the method of substitution.
First, let's solve the first equation for x:
x = 34 - y - z
Now, we substitute this value of x into the second equation:
1(34 - y - z) + 10y + 5z = 100
34 - y - z + 10y + 5z = 100
34 + 9y + 4z = 100
Next, we simplify the second equation:
9y + 4z = 100 - 34
9y + 4z = 66
We can rewrite this equation as:
9y = 66 - 4z
y = (66 - 4z) / 9
Now, we substitute this value of y back into the first equation:
x + (66 - 4z) / 9 + z = 34
Multiplying through by 9 to eliminate the fraction:
9x + 66 - 4z + 9z = 306
9x + 5z = 240
Now we have a system of two equations in two variables:
9x + 5z = 240
9y + 4z = 66
We can solve this using the method of substitution or elimination. Let's use the method of elimination:
Multiplying the first equation by 4 and the second equation by 5, we get:
36x + 20z = 960
45y + 20z = 330
Subtracting the second equation from the first, we eliminate z:
36x - 45y = 630
We can simplify this equation by dividing through by 9:
4x - 5y = 70
Now, let's solve the new system of equations:
4x - 5y = 70
9y + 4z = 66
We can multiply the first equation by 9 and the second equation by 4 to eliminate x:
36x - 45y = 630
36y + 16z = 264
Now, subtracting the first equation from the second, we eliminate y:
36y + 16z - 36x + 45y = 264 - 630
81y + 16z = -366
Dividing through by 3, we get:
27y + 16z = -122
Now, we have a system of two equations in two variables:
4x - 5y = 70
27y + 16z = -122
We can solve this system using the method of substitution or elimination.

Answer:
Jillian is Incorrect as fraction can never be balanced based on numerator or denominator.
Step-by-step explanation:
Given:
Measure of ribbon Kiara has =
Measure of ribbon Jillian has =
Now given:
Jillian says their ribbons are equal in length because her numerator is one more than kiara's and her denominator is one less, therefore balancing the two fractions.
we need to find whether statement is correct or not.
First we will find the decimal value of the given fraction's
can rewritten as
Measure of ribbon Kiara has = 0.25 inch
can be Rewritten as
Measure of ribbon Jillian has = 0.67 inch
Now we can see that;
0.67 inch is greater than 0.25 inch.
Hence we can say that ribbons are not in equal length.
Also the fraction can never be balanced by decreasing or increasing the numerator or denominator.
