Suppose chocolate costs $17.60 per kilogram. Karega buys 25 grams of chocolate and Samadhi buys 100 grams of chocolate. How much more did Samadhi pay for her chocolate?

Samadhi paid $ 1.32 more than Kerega.

Step-by-step explanation:

We were given the price of chocolate per kilogram, but Karega and Samadhi bought it in grams, so in order to solve this question we will convert the amount they bought from grams to kilograms, to do that we divide the value by 1000. So we have:

Karega = (25 grams)/1000 = 0.025 kg

Samadhi = (100 grams)/1000 = 0.1 kg

In order to find how much each paid for their chocolate we have to multiply the amount the bought in kg by the price per kg. So we have:

Kerega = (0.025)*17.6 = $ 0.44

Samadhi = (0.1)*17.6 = $ 1.76

To know how much more Samadhi paid we have to subtract the amount she paid by the amount Kerega paid. We have:

difference = Samadhi - Kerega = 1.76 - 0.44 = $ 1.32

Samadhi paid $ 1.32 more than Kerega.
