Hi!
So, x is going to be the price of one apple. We need to solve for x, so let's start with getting an equation up and running.
<em>3x + 0.84 = 5x
Now, we're going to subtract three from both sides.
3x - 3x + 0.84 = 5x - 3x
Now, we're going to divide 2 from both sides!
0.84 / 2 = 2x / 2
And our final answer is... 0.42 for each apple! =)

Use a calculator to find that
7.095*2.55 = 18.09225
Then round to the nearest tenth to get 18.1
Why the nearest tenth? Because we want the answer to have 3 sig figs. This is the smallest number of sig figs between the two original numbers (7.095 and 2.55).
Answer: Choice D) 18.1
Given:
Focus of a parabola =
Directrix:
To find:
The equation of the parabola.
Solution:
The equation of a vertical parabola is:
...(A)
Where, is center, is focus and is the directrix.
On comparing the focus, we get
...(i)
On comparing the directrix, we get
...(ii)
Adding (i) and (ii), we get
Putting is (i), we get
Putting in (A), we get
On further simplification, we get
Therefore, the equation of the parabola is .
Note: Option C is correct but the leading coefficient should be negative.
