You invest $15,000 to start a hot dog stand at the local sports complex. It costs you $.65 to produce each hot dog. How many hot

SCORPION-xisa [38]

Answer:

Below is the procedure to find the answer: 30,000 hot dogs.

Explanation:

The <em>average cost </em>is found dividing the total cost by the number of hot dogs:

$Average\text{ }cost=Total\text{ }cost/Number\text{ }of\text{ }hot\text{ }dogs$

The total cost is the the sum of amount that you invest plus the product of the cost of producing each hot dog times the number of hot dogs:

$Total\text{ }cost=investment+Number\text{ }of\text{ }hot\text{ }dogs\times cost\text{ }to\text{ }produce\text{ }each\text{ }hot\text{ }dog$

Substitute the values:

$Total\text{ }cost=15,000+0.65x\\ \\ Averate\text{ }cost=(15,000+0.65x)/x=1.15$

Where x is the number of hot dogs.

Solve for x from the equation:

$(15,000+0.65x)/x=1.15\\ \\ 15,000+0.65x=1.15x\\ \\ 15,000=1.15x-0.65x\\ \\ 15,000=0.5x\\ \\ 15,000/0.5=x\\ \\ 30,000=x\\ \\ x=30,000$

Which shows you how you can find that the answer is 30,000 hot dogs.

Tell whether x=6 is a solution of x−1 ≤ 7.

MrRa [10]

Answer:

x = 6 is a solution of x - 1 $\leq$ 7.

Step-by-step explanation:

First, plug in x = 6 into the inequality.

x - 1 $\leq$ 7 for x = 6

6 - 1 $\leq$ 7

Now, solve.

6 - 1 = 5

5 $\leq$ 7

The statement above is true, so x = 6 is a solution to x - 1 $\leq$ 7.

Please inform me of any mistakes.
