Answer 1
Answer: 18, 17, 11, 18, 14, 14, 15, 18, 13, 12, 20, 17

Step One: Put them in numerical order.

11, 12, 13, 14, 14, 15, 17, 17, 18, 18, 18, 20

Step Two: Cross out one from each side until you are left with one or two in the center. (ones that are crossed out will be bolded for our purposes)

11, 12, 13, 14, 14, 15, 17, 17, 18, 18, 18, 20

Step Three: Since two numbers are left in the middle, the median is the number in the middle of the two.

Median = 16 (B)

What is 1/10 divided by 9/10?

Answers

1/10 divided by 9/10

Answer:

1/10 divided by 9/10 is 1/9

Step-by-step explanation:

It is 1/9 because 1/10 divided by 9/10 is the same as using the reciprocal of 9/10 which then now you have 1/10 multiply by 10/9 and you have 10/90 which is simplified to 1/9.

The Retread Tire Company recaps tires. The fixed annual cost of the recapping operation is $65,000. The variable cost of recapping a tire is $7.5. The company charges$25 to recap a tire. a. For an annual volume of 15, 000 tire, determine the total cost, total revenue, and profit. b. Determine the annual break-even volume for the Retread Tire Company operation.

Answers

Part a) Total Cost

Total Cost for recapping the tires is the sum of fixed cost and the variable cost. i.e.

The total cost is ( $65,000 fixed) + (15,000 x $7.5)

=$65,000+$112,500

=$177,500  

Part b) Total Revenue

Revenue from 1 tire = $25

Total tires recapped = 15000

So, Total revenue = 15000 tires x $25/tire

Total Revenue =$375,000  

Part c) Total Profit

Total Profit = Revenue - Cost

Using the above values, we get:

Profit = $375,000 - $177,500

Profit = $197,500  

Part d) Break-even Point

Break-even point point occurs where the cost and the revenue of the company are equal. Let the break-even point occurs at x-tires. We can write:

For break-even point

Cost of recapping x tires = Revenue from x tires

65,000 + 7.5 x = 25x

65,000 = 17.5 x

x = 3714 tires

Thus, on recapping 3714 tires, the cost will be equal to the revenue generating 0 profit. This is the break-even point.
