I need help please.
Assume that one dollor is equal to 1.14 euros. If 500 g of an item is selling for 25 euros, what is its price in dollars per kg?
1 dollar / 1.14euros = ?/25 euros
cross multiply to get
dollars = 1.14(25)
Multiply and you will have dollars.
1000 g = 1 kg
you have 500 g = 1/2 kg
divide your dollars by 1/2 which is the same thing as multiplying by 2 and you will have dollars/kg
To find the price in dollars per kilogram, we need to convert the price from euros to dollars and then determine the price per kilogram.
Given that 1 dollar is equal to 1.14 euros, we can find the price in dollars by dividing the price in euros by the exchange rate:
Price in dollars = Price in euros / Exchange rate
Price in dollars = 25 euros / 1.14 euros
Price in dollars = 21.93 dollars (rounded to two decimal places)
Now, to find the price per kilogram, we need to convert the price per gram to the price per kilogram:
Price per kilogram = Price in dollars / Weight in kilograms
Since we are given that the weight is 500 grams, we need to convert it to kilograms by dividing by 1000:
Weight in kilograms = 500 grams / 1000
Weight in kilograms = 0.5 kilograms
Finally, we can calculate the price per kilogram:
Price per kilogram = 21.93 dollars / 0.5 kilograms
Price per kilogram = 43.86 dollars per kilogram
Therefore, the price of the item in dollars per kilogram is 43.86 dollars.
To calculate the price in dollars per kilogram, you will need to convert both the price and the weight to the desired units.
Let's start by converting the price of the item from euros to dollars. Since $1 is equal to €1.14, we can calculate the conversion as follows:
Price in dollars = Price in euros * Conversion rate
Price in dollars = 25 euros * 1.14 dollars/euro
Price in dollars = $28.50
Next, we need to convert the weight from grams to kilograms. There are 1000 grams in a kilogram, so we can calculate the conversion as follows:
Weight in kilograms = Weight in grams / 1000
Weight in kilograms = 500 grams / 1000
Weight in kilograms = 0.5 kg
Finally, to find the price in dollars per kilogram, divide the price in dollars by the weight in kilograms:
Price in dollars per kilogram = Price in dollars / Weight in kilograms
Price in dollars per kilogram = $28.50 / 0.5 kg
Price in dollars per kilogram = $57.00/kg
Therefore, the price of the item in dollars per kilogram is $57.00.
