Suppose the eggplants at a store in Thailand are priced at 1.24 baht per kilogram, where one dollar is worth 1.37 baht. What is the price of the eggplants in dollars per pound?
1.24 baht / kg
$1=1.37 baht, 1 baht = 1/1.37$
1 kg=2.2 lbs
Substitute 1 baht and 1 kg into the above expression (1.24 baht/kg)
and simplify.
To find the price of the eggplants in dollars per pound, we'll need to convert the Thai baht price per kilogram to dollars per pound.
First, let's convert the Thai baht price per kilogram to dollars per kilogram. Since one dollar is worth 1.37 baht, we can divide the Thai baht price by the exchange rate:
Thai baht price per kilogram = 1.24 baht
Exchange rate: 1 dollar = 1.37 baht
Price in dollars per kilogram = 1.24 baht / 1.37 baht/dollar
Price in dollars per kilogram = 0.904 dollars
Now that we have the price in dollars per kilogram, we can convert it to dollars per pound. There are 2.20462 pounds in a kilogram, so we divide the price in dollars per kilogram by the conversion factor:
Price in dollars per kilogram = 0.904 dollars
Conversion factor: 1 kilogram = 2.20462 pounds
Price in dollars per pound = 0.904 dollars / 2.20462 pounds
Price in dollars per pound ≈ 0.41 dollars
Therefore, the price of the eggplants in dollars per pound is approximately 0.41 dollars.
