Aclerk is marking up merchandise 34%. the original price of an item is $455. what will be the retail price?

$609.70

Step-by-step explanation:

Given : A clerk is marking up merchandise 34%.

The original price of an item is $455.

Then, the Mark up price = 34% of Original price

⇒ Mark up price   [Replace 'of' by '× 'and convert percentage into decimal by dividing it by 100 ]

⇒ Mark up price= $154.70

Now , Retail price = Original price + mark up price

= $455+$154.70 =$609.70

Therefore , the retail price will be $609.70 .

explanation

the graph has a slope of 1/3 because each time you move up 1, you go to the right 3. so, slope = rise/run = 1/3. we can cross choice a off the list since we want a slope of 3, rather than 1/3.

the first table shown has a slope of -3. this is because the rise is -6 and the run is 2, so slope = rise/run = -6/2 = -3. note how x increases by 2 each time (run) and y drops by 6 each time (rise). choice b can be eliminated.

the second table has a slope of 3. each time x goes up by 1, the y values increase by 3. slope = rise/run = 3/1 = 3. alternatively you can use the slope formula to prove that the slope is 3 here. use any two rows of values to generate the two points. choice c is one of the answers

the third table also has a slope of 3. let's use the slope formula to prove as such. i'm going to use the first two rows of the table. so i'll use the two points (2,1) and (5,10)

m = slope

m = (y2-y1)/(x2-x1)

m = (10-1)/(5-2)

m = 9/3

m = 3 so we get a slope of 3

choice d is the other answer
