Answer:

Rs.15

Step-by-step explanation:

The stationer sold 1 dozen of pens, meaning he sold 12 pens.

He gained Rs.120, meaning he gained Rs.(120/12) = Rs.10 for each pen.

Hence, the cost price was Rs.(25 - 10)

= Rs.15

Hope this helped!

An inequality is used to show two values that are different and to show that the two values are unequal.

<h3>What is an Inequality?</h3>

This refers to the mathematical relation that is used to show the comparison between two numbers that are unequal.

We can note that because there is a previous record, for a person to beat the record, he would have to perform better than the record and be faster than the previous record holder.

Therefore, if a record of Amelia was given, this would be used to find the relation between her record and the current record of 37 sit-ups and how many weeks of training would be needed to break the record.

Hence, we can see that the question is incomplete so I gave you a general overview to help you get a better understanding.

Find the slope line (-2 -1) and (-4 -7)
Alenkinab [10]

Answer:

m=3

Step-by-step explanation:

Slope formula

m=\frac{y_2-y_1}{x_2-x_1}

Here

(x_1, y_1) = (-2, -1) \ \ and \ \ (x_2, y_2) = (-4, -7)

Slope can be calculated as

m=\frac{-7-(-1)}{-4-(-2)}

m= \frac{-6}{-2} \\m=3
