To ensure profits, a store is going to sell a sweater for 115 percent of the production cost. It costs $10 to make the sweater. Below are the calculations for finding the selling price. What mistake did the store owner make? (Original Cost)(Percent) = New Cost ($10)(0.115) = $1.15 The new cost is correct. The owner should have divided by 0.115. The owner should have multiplied by 11.5. The owner should have multiplied by 1.15.
Answer:I did the test and the answer is The owner should have multiplied by 1.15.
Step-by-step explanation:
Sample text
To make the calculation 115 percent of the production cost , the owner should have multiplied by 1.15 to the production cost.
What is percentage?" Percentage is defined as the hundredth part of any given number".
According to the question,
Production cost of a sweater = $10
To ensure profit , selling price = 115 percent of the production cost
(Original Cost)(Percentage)
[tex]= (10)(\frac{115}{100} )[/tex]
[tex]= $11.5[/tex]

3x(x+30°) i really need help asap
A13x2+390x here is the answer
Answer:
x=15
Step-by-step explanation:
Simplifying
x + 30 = 3x
Reorder the terms:
30 + x = 3x
Solving
30 + x = 3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3x' to each side of the equation.
30 + x + -3x = 3x + -3x
Combine like terms: x + -3x = -2x
30 + -2x = 3x + -3x
Combine like terms: 3x + -3x = 0
30 + -2x = 0
Add '-30' to each side of the equation.
30 + -30 + -2x = 0 + -30
Combine like terms: 30 + -30 = 0
0 + -2x = 0 + -30
-2x = 0 + -30
Combine like terms: 0 + -30 = -30
-2x = -30
Divide each side by '-2'.
x = 15
Simplifying
x = 15

4x-6=x+9 i need help can someone show the work too please
Answer:
x = 5
Step-by-step explanation:
instructions in pic :)
4x - 6 = x + 9
4x - 6 - x - 9 = x + 9 - x - 9 [Subtract x + 9 from both sides]
3x - 15 = 0
3x - 15 + 15 = 0 + 15 [Add 15 to both sides]
3x = 15
3x/3 = 15/3 [Divide both sides by 3]
x = 5

It is given that JKLM is a parallelogram, so JM ll KL by the ____
. Therefore, ∠1 ≅∠2 by the corresponding angles postulate. Also, it is given that _____ ≅∠3, so ∠1≅ ____by the ____
JM is parallel to KL by the definition of parallelogram (opposite sides of any parallelogram are parallel)
Therefore, angle 1 = angle 2 by the corresponding angles postulate
We're also given angle 2 = angle 3
So angle 1 = angle 3 by the transitive property of congruence
