Answer: No, Store A is charging $2.20 per rose while Store B is charging 2.166667 dollars per rose.

Step-by-step explanation:

11/5 = 2.2

(To check) 2.2 x 5 also equals $11

However, they are not selling roses at the same rate because if you were to do 2.2x6 it will equal 13.2.

13/6 = 2.166667

A conservative estimate of the number of stars in the universe is 6 x 10^22. The average human can see about 3,000 stars at nigh

Ilia_Sergeevich [38]

$2 \times 10^{19}$ times more stars are there in universe compared to human eye can see

<h3>Solution:</h3>

Given that, conservative estimate of the number of stars in the universe is $6 \times 10^{22}$

The average human can see about 3,000 stars at night with only their eyes

To find: Number of times more stars are there in the universe, compared to the stars a human can see

Let "x" be the number of times more stars are there in the universe, compared to the stars a human can see

Then from given statement,

$\text{Stars in universe} = x \times \text{ number of stars human can see}$

Substituting given values we get,

$6 \times 10^{22} = x \times 3000\\\\x = \frac{6 \times 10^{22}}{3000}\\\\x = \frac{6 \times 10^{22}}{3 \times 10^3}\\\\x = 2 \times 10^{22-3}\\\\x = 2 \times 10^{19}$

Thus $2 \times 10^{19}$ times more stars are there in universe compared to human eye can see

You are the manager of a donut shop. Presently, you sell your donuts for $1.00 each and everyday you sell 500 donuts. However, y

never [62]

Answer: $1.75

Solve for:

What price would result in the most revenue?

Step-by-step explanation:

Let the price of one donut = 1 + 0.05x

Let the # of donuts he can sell = 500 - 10x

Revenue,

$R(x) = (1 + 0.05x)(500 - 10x)$

$R(x) = 500 - 10x + 25x - 0.5x^2$

$R(x) = -10 + 25-0.5(2x)$

$= 15-x\\x=15$

Revenue is maxed when x = 15

When the revenue is maxed,

$Price = 1 + 0.05(15)\\=1 + 0.75\\=1.75$

Therefore the best price for this scenario is $1.75
