Helen calculated that she paid $1.50 per 100g for the usable part of the fish. How did
Helen calculate $1.50?
To calculate that she paid $1.50 per 100g for the usable part of the fish, Helen must have divided the total amount she paid by the weight of the usable part of the fish. Here's how you can calculate it step by step:
1. Determine the total amount Helen paid for the fish. Let's say she paid $X.
2. Determine the weight of the usable part of the fish. Let's say it weighs Y grams.
3. Divide the total amount paid by the weight of the usable part to find the cost per gram: X / Y.
4. Since the given price is per 100 grams, multiply the cost per gram by 100 to find the cost per 100g: (X / Y) * 100.
Based on the given information, Helen must have divided the total amount she paid by the weight of the usable part of the fish and obtained $1.50 as the cost per 100g.
