the shopkeeper sold a laptop having its cost price rupees 25000 at a profit of 25% find its selling price ​

Answers

Answer:

Let's see what we have here. A shopkeeper sold Item X for a his selling price (SP).

Let SP = x

Since the question says that Profit is 25% of the selling price, we have:

Profit = 25% SP = 0.25x

Now, we already know that:

Profit = SP - Cost

This part is the catch. To find out how much Item X originally cost,

Cost = SP - Profit = x - 0.25x = 0.75x

Now that we know the original cost of Item X, we can easily calculate the Real profit % using this formula:

= (Profit/Cost)*100

= (0.25x/0.75x)*100

= 33%

And there you have it. Hope I explained it clear enough.

Answer:

Step-by-step explanation:

Cost price = CP = ₹ 25,000

Profit% = 25%

Selling price = SP

[tex]SP =\dfrac{100+profit}{100}*CP\\\\\\=\dfrac{100+25}{100}*25000\\\\=\dfrac{125}{100}*25000[/tex]

= 125 * 250

= ₹31250

6. What type of slope does the equation
7x + 3y = 15 have? (Hint: convert to slope
intercept form.)
A) positive
B) Negative
C) Zero
D) Undefined

Answers

Answer: B) Negative

Step-by-step explanation:

We can convert the line 7x + 3y = 15 into the slope-intercept form (y = mx + c) by making y the subject of the equation. In this form the coefficient of x (m) is the slope.

Since 7x + 3y = 15

                 3y = -7x + 15

                   y = - ⁷/₃x + 5

∴ the slope is NEGATIVE.

Check your answer:

A line with a negative slope is highest to the left and lowest to the right. This is because when x values increase, the y  values decrease, and when x values decrease, y values increase (the two variables are negatively related). If we graph the line this should be true, and it is.

What are polynomials forms?

Generally, polynomials take the form,

P(x) = ax^n + bx^(n-1) + cx^(n-2).... + z

where:

a, b....= arbitrary constants

x = variable

n = highest power of the variable in the polynomial

The given polynomial is P(x) = x^3−1

Tony and Suzie are ready to expand Great Adventures even further in 2022. Tony believes that many groups in the community (for example, Boy Scouts, church groups, civic groups, and local businesses) would like to hold one-day outings for their members. Groups would engage in outdoor activities such as rock climbing, fishing, capture the flag, paintball, treasure hunts, scavenger hunts, nature hikes, and so on. The purpose of these one-day events would be for each member of the group to learn the importance of TEAM (Together Everyone Achieves More).Tony knows that most people are not familiar with these types of activities, so to encourage business he allows groups to participate in the event before paying. He offers a 4% quick-payment discount to those that pay within 10 days after the event.
