The cost function is
c = 0.000015x² - 0.03x + 35
where x = number of tires.
To find the value of x that minimizes cost, the derivative of c with respect to x should be zero. Therefore
0.000015*2x - 0.03 = 0
0.00003x = 0.03
x = 1000
Note:
The second derivative of c with respect to x is positive (= 0.00003), so the value for x will yield the minimum value.
The minimum cost is
Cmin = 0.000015*1000² - 0.03*1000 + 35
= 20
Answer:
Number of tires = 1000
Minimum cost = 20

Step-by-step explanation:
<u>Step 1: Define</u>
2(3x - 1) ≥ 4x - 6
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute 2: 6x - 2 ≥ 4x - 6
- Subtract 4x on both sides: 2x - 2 ≥ -6
- Add 2 on both sides: 2x ≥ -4
- Divide 2 on both sides: x ≥ -2
Here we see that any value <em>x</em> greater than or equal to -2 would work as a solution.
