the price of grapes at the grocery store is $1.44 per pound. there are approximately 0.45 kilograms in a…

Explanation:

Step1: Understand the conversion

We know the price per pound ($1.44) and the number of kilograms in a pound (0.45 kg). To find the price per kilogram, we need to divide the price per pound by the number of kilograms in a pound.

Step2: Set up the calculation

The formula to find the price per kilogram ((P_{kg})) is (P_{kg}=\frac{\text{Price per pound}}{\text{Kilograms per pound}}). Substituting the given values: (P_{kg}=\frac{1.44}{0.45}).

Step3: Perform the division

Calculating (\frac{1.44}{0.45}), we can multiply numerator and denominator by 100 to eliminate decimals: (\frac{144}{45} = 3.2). Wait, no, wait. Wait, 0.45 kg is 1 pound, so to get per kg, we need to see how much for 1 kg. Wait, no: if 0.45 kg costs $1.44, then 1 kg costs $1.44 / 0.45. Let's calculate that: 1.44 divided by 0.45. 0.45 times 3 is 1.35, 1.44 - 1.35 is 0.09, 0.09 / 0.45 is 0.2, so total is 3.2. Wait, but let's check the options. Wait, the options include $3.20 per kilogram. Wait, did I do that right? Let's recheck: price per pound is $1.44, and 1 pound is 0.45 kg. So to find price per kg, we do 1.44 / 0.45. Let's compute that: 1.44 ÷ 0.45. Multiply numerator and denominator by 100: 144 ÷ 45. 45×3 = 135, 144 - 135 = 9, 9/45 = 0.2, so 3 + 0.2 = 3.2. So the price per kilogram is $3.20.

Answer:

D. $3.20 per kilogram
