For this case we must follow the following rules of rounding

1) If the previous number is greater than or equal to five, then the next number increases by one unit

2) If the previous number is less than five, then the next number stays the same

Therefore, the steps for rounding to the nearest tenth is:

1) We observe that 3 is less than 5.

2) Therefore, the next number stays the same

Rounding to the nearest tenth is:

5.6

Answer:

1) We observe that 3 is less than 5.

2) Therefore, the next number stays the same

5.6

The function C(x)=−20x+1681 represents the cost to produce x items. What is the least number of items that can be produced so th
Reptile [31]

Answer:

<em>The least number of items to produce is 41</em>

Step-by-step explanation:

<u>Average Cost</u>

Given C(x) as the cost function to produce x items. The average cost is:

\displaystyle \bar C(X)=\frac{C(x)}{x}

The cost function is:

C(x) = -20x+1681

And the average cost function is:

\displaystyle \bar C(X)=\frac{-20x+1681}{x}

We are required to find the least number of items that can be produced so the average cost is less or equal to $21.

We set the inequality:

\displaystyle \frac{-20x+1681}{x}\le 21

Multiplying by x:

-20x+1681 \le 21x

Note we multiplied by x and did not flip the inequality sign because its value cannot be negative.

Adding 20x:

1681 \le 21x+20x

1681 \le 41x

Swapping sides and changing the sign:

41x \ge 1681

Dividing by 41:

x\ge 41

The least number of items to produce is 41
