Bir kırtasiyeci aldığı kalemlerin tanesini

andrew11 [14]

Answer: Option B: 120.

Step-by-step explanation:

I will answer in English

This problem can be translated to:

A man bought N pens, (at a cost C) if he sells each pen at 2 lira, he will have a profit of 40 lira.

If he sells each pen at 1.5 lira, he will loss a total of 20 lira.

We want to find N, the number of pens that he bought.

if he sells the N pens at 2 lira each, the revenue is:

N*2 lira

And the profit is the difference between the revenue and the cost, then the profit (40 lira in this case) is:

N*2 lira - C = 40 lira.

When he sells each pen at 1.5 lira the equation is:

N*(1.5 lira) - C = -20 lira.

Then we have two equations:

N*2 lira - C = 40 lira.

N*(1.5 lira) - C = -20 lira.

To solve this we need to isolate the variable C in one of the equations, i will isolate C in the second equation:

N*(1.5 lira) + 20 lira = C.

Now we can replace this in the first equation to get:

N*(2 lira) - (N*(1.5 lira) + 20 lira) = 40 lira.

We can solve this for N.

N*(2 lira) - N*(1.5 lira) - 20 lira = 40 lira

N*(2 lira - 1.5 lira) = 60 lira

N*(0.5 lira) = 60 lira

N = (60lira/0.5lira) = 120

N = 120

This means that he bought 120 pens.

The correct option is B.

Anna’s cell phone plan charges her $30 per month plus a $150 one-time activation fee. Evelyn’s cell phone plan charges her $20 p

AveGali [126]

Given:

Anna’s cell phone plan charges her $30 per month plus a $150 one-time activation fee.

Evelyn’s cell phone plan charges her $20 per month, plus a $450 one-time activation fee.

To find:

The number of months after which the costs for the girls’ cell phone plans the same.

Solution:

Let x be the number of months.

Total cost = Fixed cost + Variable cost

According to the question, cost equation for Anna’s cell phone is

$y=150+30x$ ...(i)

Cost equation for Evelyn's cell phone is

$y=450+20x$ ...(ii)

Equate (i) and (ii) to find the time after which the costs for the girls’ cell phone plans the same.

$150+30x=450+20x$

$30x-20x=450-150$

$10x=300$

Divide both sides by 10.

$x=\dfrac{300}{10}$

$x=30$

Therefore, the costs for the girls’ cell phone plans the same after 10 months.

Aleksandr-060686 [28]

Answer:

Step-by-step explanation:

2 liters = 2,000

80/3 = 26.6

the bottle leaks 26.6 milliliters in a min

26.6*60 = 1596

1596 / 1000 = 1.596 (to convert to liters)

the bottle will leak 1.596 an hour
