Explanation:
We can start with the relations ...
Answer:
1. cost per chair: $86.40
2. selling price per chair: $146.88
Step-by-step explanation:
1. The total cost per chair will be the sum of the cost of materials and the overhead cost (equipment, energy, labor, marketing). The cost of materials is ...
$500/(16 chairs) = $31.25/chair
So, the total cost is ...
cost of each chair = material cost + overhead cost
= $31.25 +55.15
cost of each chair = $86.40
__
2. We assume the markup is 70% of the cost, so will be ...
0.70 · $86.40 = $60.48
Then the selling price of the chair will be ...
selling price = cost + markup
selling price = $86.40 +60.48
selling price = $146.88
I don't know what your story is, but in a story, usually a problem would build tension.
Hope this helps!! :)
Test the choices !
Pick an even number, and see what each choice does to it.
Let's start with, say, 6 .
We'll try each choice, and see which one produces an odd number:
a). 6 to the 2nd power. . . . . . 6 x 6 = 36. That's not an odd number.
b). 6 + 3 = 9 This could be it. 9 is odd. We'll save this one.
c). 3·6 = 18. That's not an odd number.
d). 6/3 = 2. That's not an odd number.
The only one that gave us an odd number is (b).
Melanie: 15 years old
Kevin: 5 years old
Assume Kevin's present age is x.
That means that 3 years ago, his age would be x - 3.
Melanie's age would be 6(x - 3).
Same thing for 5 years into the future:
Kevin's age would be x + 5.
Melanie's age would be 2(x + 5).
The two equations we have here are:
By subtracting both equations, we are simplified to:
8 = -4x + 28
By solving the equation, we get x = 5.
That means that Kevin's current age is 5 years old.
Melanie's age could be calculated by substituting Kevins'.
6(x - 3) --> 6(5 - 3) --> 12
Since that was 3 years ago, you need to add 3 to 12 to get her current age.
12 + 3 = 15
Melanie's current age is 15 years old.
