A pair of jeans was 30% off the original price. The sale resulted in a $24 discount.

Natalija [7]

Answer:

Step-by-step explanation:

We must consider the price of the Jeans as whole since it represents the full price of the jeans. The discount might be a limited only offer and does not represent the fullest price of the jeans.

To find the original price of the jeans we have two methods that in the end are going to lead to the same conclusion. The long method is to represent mathematically the information presented. Conceptually, we could interpret the statement saying that the original price minus 30% of the original price is equal to the original price minus the discount. Let us say the Original Price (OP)=x. then, mathematically we represent the statement as:

$x -0,3*x = x -24$

What we need to do now is to isolate x on one side of the equation. We have x as a common factor, so:

$x*(1-0,3)=x-24 \rightarrow 24+x*0,7=x$

$24=x-0,7*x \rightarrow 24 = x*(1-0,7)$

$24 = 0,3*x \rightarrow 24/0,3 =x \rightarrow x=80$

This one is the original price of the jeans: $80. There is a shortcut to this method, though. We know two things that are fundamental: the discount sale is $24 and the jeans are 30% off. These statements provide the same information; thus we can match them and say that:

$24 = 0,3*x \rightarrow 24/0,3 =x \rightarrow x=80$

And we find ourselves on the same conclusion.

Have a wonderful day :D

There are 10 students in a class. The teacher chooses 2 students to go to the

CaHeK987 [17]

Answer:

The number of ways in which students were chosen is 45 ways .

Step-by-step explanation:

Given as :

The number of students in a class = x = 10

The number of students chosen by teacher to go to library = y = 2

Let The number of ways in which students were chosen = n ways

Now, According to question

So, number of ways in which students were chosen = $_{y}^{x}\textrm{C}$

Or, n ways = $_{2}^{10}\textrm{C}$

Or, n = $\frac{\L 10}{\L( 10-2)\times \L 2}$

Or, n = $\frac{\L 10}{\L8\times \L 2}$

Or, n = $\frac{10\times 9\times \L 8}{\L 8\times \L 2}$

Or, n = $\frac{10\times 9}{2\times 1}$

Or, n = 5 × 9

i.e n = 45

So, The number of ways in which students were chosen = n = 45 ways

Hence,The number of ways in which students were chosen is 45 ways . Answer

As a dietitian, your patient is on a low sodium diet (less than 1,100 mg of sodium per meal). She has a breakfast of orange juic

erastovalidia [21]

You need a table with the content of sodium per serving.

This is the table:

butter 1 pat 41mg

coffe 250 ml 0

eggs 1 serving 60mg

toast 1 slice 170mg

orange
juice 250 ml 4 mg

With that table you can calculate the content of sodium in the breakfast, this way:

orange juice: 1 * 41 mg = 4 mg
2 eggs: 2*60mg = 120 mg
2 slices of toast with butter on each: 2 * ( 170mg+41mg) = 422mg
and coffee: 1 *0 = 0

The total sodium ingested is: 4 mg + 120 mg + 422 mg = 546 mg

Answer: 546 mg
