Answer:

No, it is 6.60

Step-by-step explanation:

We need to know the cost of 1 pound, so we have to do 3.60 divided by 3, to get the cost of 1 pound, which is 1.20

We times 1.20 by the amount of pounds we need, (5.5,) and get 6.60.

If it was times just 5 pounds, than yes, it would be correct, but we need to look out for decimals too.

Answer:

d. $6.60

Step-by-step explanation:

3 cost 3.60, then 5.5 would cost ?

So we have to find what multiplied with 3 would equal 5.5, so:

5.5/3, we can't simplify this fraction so we'll just use it to multiply 3.60

3.60 × 5.5/3 = 19.8/3 = 6.6

A jeweler wants to minimize business costs and has found that the average cost in dollars per necklace is given by C(x)=0.5x^2-7
Vika [28.1K]

Answer:

The maximum cost is 41 dollars per necklace.

Step-by-step explanation:

The average cost in dollars/necklace is given by :

C(x)=0.5x^2-7x+65.5  .....(1)

Where

x is the number of necklaces that are created

To maximize the cost, find the value of x by putting dC/dx = 0

\dfrac{d}{dx}(0.5x^2-7x+65.5)=0\\\\x-7=0\\\\x=7

Now put the value of x = 7 in equation (1).

C(x)=0.5(7)^2-7(7)+65.5\\\\=41\ \text{dollars per necklace}

Hence, the maximum cost is 41 dollars per necklace.
