Find the selling price of a $270 by bicycle with a 24% markup

Answers

first find what 24% of 270 is. multiply .24 times 270 to get 64.8. Then add 64.8 to 270 to get the markup price. 
334.8

270 times .24 (which is equal to 24%) is equal to 64.8. You add that to the 270. 64.8+270=334.8!

In a salsa recipe, the number of tomatoes added is proportional to the amount of salt added. This graph shows the relationship.What is the unit rate for the situation?









A.


3 tomatoes per teaspoon of salt


B.


6 tomatoes per teaspoon of salt


C.


18 tomatoes per teaspoon of salt


D.


108 tomatoes per teaspoon of salt

Answers

The unit rate for the situation is 3 tomatoes per teaspoon of salt.

The equation of a straight line is given by:

y = mx + b;

where m is the slope of the line, b is the y intercept and y, x are variables.

y represent the number of tomatoes added and x represent the number of teaspoon of salt.

Given the equation of the line is: y = 3x

The unit rate of the graph is equal to the slope of the graph (i.e. 3). Hence:

The unit rate for the situation is 3 tomatoes per teaspoon of salt.

For this case, the first thing you should keep in mind is that the generic equation of the line is:

Where,

m: slope of the line or rate of cam.

b: cutting point with vertical axis.

We note that for this case, the equation of the line is:

Therefore we have:

This means that 3 tomatoes are added for each teaspoon of salt.

-PLEASE HURRY- this is the third time I’ve asked this question and no one has given me an answer.How do I evaluate/solve multi-step expressions?

Answers

Answer:

Step-by-step explanation:

Solve 3y + 10.5 = 6.5 + 2.5y.

Add -2.5y to both sides so that the variable remains on one side only. Now isolate the variable by subtracting 10.5 from both sides. Multiply both sides by 10 so that 0.5y becomes 5y, then divide by 5. Check your solution by substituting -8 in for y in the original equation.

Suppose you go shopping for a new futon bed for your room. The model you really like happens to be on sale for $425. It's original price is $500. What percent of the original price will you save if you purchase it?

Answers

Answer:


Step-by-step explanation:

What you are asking is to fill in the blank in the following sentence.

_______ % off this imported futon.

Solution

500 x/100 = 425       Divide the left by 100

5x = 425                    Divide both sides by 5

5x/5 = 425/5             Simplify

x = 85

That is not the answer. That is the % paid.

The reduction is 100% - 85% = 15%

So your blank would contain 15%

Check

15% of 500 = 15/100 * 500 = 75 which is what they the store is offering you off.
