A company sells dog treats. The company's fixed and variable costs are modeled by the function C(x)=1.4x+2000. Their revenue is
Naya [18.7K]

<u>Answer:</u>

<u>20,000 packages.</u>

<u>Step-by-step explanation:</u>

The rest of the question is as following:

If x represents the number of packages of dog treats, how many packages do they have to sell to break even? Round your answer to the nearest whole number, and do not include units.

=========================================

The function of fixed and variable costs ⇒ C(x) = 1.4x + 2000

The function of revenue ⇒ R(x) = 1.5x

The even situation will happen when costs = revenue

∴ C(x) = R(x)

∴ 1.4 x + 2000 = 1.5x

Solve for x:

∴ 1.5x - 1.4x = 2000

∴ 0.1 x = 2000

∴ x = 2000/0.1 = 20,000

The even will happen when they sell <u>20,000</u> packages

So, To break even, they have to sell more than 20,000 packages .

<h3>Option A:</h3>

291=2(145)+3\\\\291=290+3\\\\\boxed{291\neq 293}

Option A is not a solution.

<h3>Option B:</h3>

163=2(78)+3\\\\163=156+3\\\\\boxed{163\neq 159}

Option B is not a solution.

<h3>Option C:</h3>

77=2(37)+3\\\\77=74+3\\\\\boxed{77=77}

7 digit number 8,920,000 when rounded to nearest 10 thousand. Digits in tens &amp; hundreds are the least &amp; same value. Valu
kirill [66]
First we can conclude that the number is:
8,9 x x, x x x ( 7-digit number ) and the value of ten thousand digit it 1 or 2. But if value of thousand digits must be the double of the value of ten thousand digits, then the number is:
8,924, x x x ( because it can not be 8,912, x x x - that number should be 8,910,000 rounded to a ten thousand digit ).
Then tens and hundreds are same and the least value. That value is zero.
8,924,00 x.
Finally, we add up all values and subtract it from 24.
24 - ( 8 + 9 + 2 + 4 + 0 + 0 ) = 24 - 23 = 1
Answer:
This number is 8,924,001.
