Answer:
The coordinates of A would be (-1, 2)
Step-by-step explanation:
In order to find this, use the mid-point formula.
(xA + xB)/2 = xM
In this, the xA is the x value of point A, xB is the x value of point B, and xM is the x value of M. Now we plug in the known information and solve for xA.
(xA + 5)/2 = 2
xA + 5 = 4
xA = -1
Now we can do the same using the midpoint formula and the y values.
(yA + yB)/2 = yM
(yA + 10)/2 = 6
yA + 10 = 12
yA = 2
This gives us the midpoint of (-1, 2)
Either $8.18 or $8.10 -
Take %10 off of $10, and we are left with $9.
Now, we know that you are going to make a profit of %10 of whatever the cost was. Let x be the cost of the product. The cost of the product plus your profit margin must equal 9. Therefore:
x + 0.10x = 9
1.1x = 9
x = 8.18
The only thing is, I'm not sure if a profit margin of ten percent means you receive %10 of the cost (in which case this answer is correct), or %10 of the $9 (in which case the cost is $8.10). It's more a case of wording than math.
But if I had to, I'd answer $8.18. Maybe someone else can confirm.
