Keiko paid $21 for a jacket.The jacket is on sale for 30% of the original price.What wa the original price of the jacket?

Answers

30/100=3/10
3 divided by 21 = 7
7*10 = 70!



The anwser is $70 I hoped that helped :3
If you assume that the original price of the jacket equals X, that means that when it was on sale, the equation to finding the price after the 30% sale would be (1-0.3)X=21 (since 30% of X would mean that Keiko should've paid 70%). That would simplify to 0.7X=21. Therefore, the original price (X) will be $30.

A rectangular garden measures 29 ft by 37 ft. surrounding (and bordering) the garden is a path 2 ft wide . find the area of this path.

Answers

Answer: The area of the path is 280 ft^2

(Note that 280 ft^2 means “280 feet squared”)

Step-by-step explanation: The first clue in this question is the dimensions of the rectangular garden which have been given as 29 ft by 37 ft. So we can conveniently compute the area of the garden as follows;

Area = L x W

(Length is 37 ft and Width is 29 ft)

Area = 37 x 29

Area = 1037 ft^2

However there is a path surrounding the garden which is 2 ft wide on all four sides. This means both borders of the length have an extra 4 feet of measurement while both borders of the width also have an extra 4 feet of measurement. So, if the surrounding border and garden is measured altogether, the length would become (37 + 4= 41) 41 feet while the width would become (29 + 4 = 33) 33 feet. So the area of the garden and the surrounding path inclusive can be calculated as

Area = L x W

Area = 41 x 33

Area = 1353 ft^2

To determine the area of ONLY THE SURROUNDING PATH, we simply deduct the area of the GARDEN ONLY (1073 ft^2) from the area of GARDEN AND SURROUNDING PATH (1353 ft^2)

Therefore area of the path surrounding the garden becomes

Area of path = 1353 - 1073

Area of path = 280 ft^2

madison bought a new phone at 20% off the original price. If she paid $320 what was the original price of the phone

Answers

Answer:

$400

Step-by-step explanation:

Hi we have to use the Rule of the Three

The price that we paid represents the 80% of the original prize

Hence we have that

$320⇒80% (.8)

$x⇒100%(.1)

As we know we have to multiply diagonally and divide with the one in the corner

So we have (320)*(1 )=320 and then divide (320)/(.8)=400

Hence the original price was $400

Answer:

400

Step-by-step explanation:

320/(1-0.2)=Original price

400x0.8=320

Why is it important to line up decimal numbers by their place value when you add or subtract them

Answers

So that you don't add the whole number to the the decimal by accident... For example: .04+ 1.0 = 1.04 but if you didn't line up the decimals and you only lined up the numbers you would have .14
So that you dont add up the whole number to the decimal part
