Given:
<span> Ballpoint Rollerball Fountain
Variation 1 2,400 1,400 550
Variation 2 3,100 2,000 370
Variation 3 2,850 1,100 720
TOTAL 8,350 4,500 1,640
</span><span>The cost of production is $1 per ballpoint pen, $2 per rollerball pen, and $4 per fountain pen.
Total cost:
8,350 x 1 = 8,350 ballpoint
4,500 x 2 = 9,000 rollerball pen
1,640 x 4 = 6,560 fountain pen
total 23,910
</span><span>Per variation:
</span>Variation 1 (2,400*1) + (1,400*2) + (550*4) = 2,400 + 2,800 + 2,200 = 7,400
<span>Variation 2 (3,100*1) + (2,000*2) + (370*4) = 3,100 + 4,000 + 1,480 = 8,580</span>
<span>Variation 3 (2,850*1) + (1,100*2) + (720*4) = 2,850 + 2,200 + 2,880 = 7,930</span>

Answer:
(x = -11 and y = 56) or (x = 1 and y = -4)
Step-by-step explanation:
The equation of the parabola is 10 + y = 5x + x² ........(1)
And 5x + y = 1 ....... (2) is the straight line.
We have to find solutions to equations (1) and (2).
Now, solving equations (1) and (2) we get, 10 + (1 - 5x) = 5x + x²
⇒ 11 - 5x = 5x +x²
⇒x² + 10x - 11 = 0
⇒ (x + 11) (x - 1) = 0
Hence, x = -11 or x = 1
Now, from equation (2),
y = 1 - 5x = 1 - 5(-11) = 56 {When x = -11}
And, y = 1 - 5(1) = -4 (When x = 1}
Therefore, the solution of the system are (x = -11 and y = 56) or (x = 1 and y = -4) (Answer)
