a vehicle factory manufactures cars. The unit cost C (the cost in dollars to make each car) depends on the number of cars made.
timofeeve [1]

Answer:

8,567

Step-by-step explanation:

Given the cost function expressed as C(x)=0.7x^2- 462 x + 84,797

To get the minimum vaklue of the function, we need to get the value of x first.

At minimum value, x = -b/2a

From the equation, a = 0.7 and b = -462

x = -(-462)/2(0.7)

x = 462/1.4

x = 330

To get the minimum cost function, we will substitute x = 330 into the function C(x)

C(x)=0.7x^2- 462 x + 84,797

C(330)=0.7(330)^2- 462 (330)+ 84,797

C(330)= 76230- 152460+ 84,797

C(330) = 8,567

Hence the minimum unit cost is 8,567

2. TANIA HAS A JOB OFFER. SHE IS OFFERED EITHER $50 PER DAY OR $30 PER DAY PLUS A COMMISSION
DerKrebs [107]
50=30+3x
(Subtract 30 from both sides)
20=3x
(Divide each side by 3)
6.67=x

She would need to sell 7 plants per day if she wanted to make at least $50 a day if she took the second deal
