Nike has decided to sell special high quality insoles for its line of basketball tennis shoes. It has fixed costs of $6 million

jenyasd209 [6]

Answer:

option (d) 800,000

Step-by-step explanation:

Let the number of pairs that must be sold be 'x'

Thus,

Total variable cost for x units = $5x

Therefore,

Total cost = Fixed cost + Total variable cost

= $6 million + $5x

Now,

Profit = Cost - Revenue

Thus,

$2 million = $15x - ( $6 million + $5x )

$2 million + $6 million = $10x

$8 million = $10x

$8,000,000 = $10x

x = 800,000

Hence,

option (d) 800,000

What is 0.2467 (467 repeating) as a fraction?

kompoz [17]

Answer:

$\frac{493}{1998}$

Step-by-step explanation:

Given

0.2467467467........

We require 2 equations with the repeating part after the decimal point.

Let x = 0.2467467....

Multiply both sides by 10

10x = 2.467467... → (1)

Multiply both sides by 10000

10000x = 2467.467467.... → (2)

Subtract (1) from (2) to eliminate the repeating part

9990x = 2465 ( divide both sides by 9990 )

x = $\frac{2465}{9990}$ = $\frac{493}{1998}$

b. 0.0001396

c. 0.001479

Step-by-step explanation:

a. Since it is a permutation with repetition the formula is:

$n^r$

Where $n$ is the number of optionss, here you will use $n_1=10$ and $n_2=26$ , one for the numbers and the other for the letters. The exponent $r$ corresponds to how many times you have to choose a number (5 times) or a letter (two times because the first letter is always the same), then:
