Answer :
Final answer:
To find the total costs, multiply the unit price by the amount for apples ($3.50 per kilo by 1 1/2 kilos to get $5.25), nuts ($9.20 per kilo by 2 1/4 kilos to get $20.70), and milk ($0.58 per liter by 3 1/2 liters to get $2.03).
Explanation:
To answer the question, we need to calculate the total cost for each item based on the given prices and quantities.
Calculating Cost of Apples
If apples cost $3.50 per kilo, to find out how much 1 1/2 kilos would cost, we multiply the price per kilo by the number of kilos:
- Multiply the cost of one kilo of apples ($3.50) by the number of kilos (1 1/2 or 1.5).
- The calculation is $3.50 * 1.5.
- The total cost for the apples is $5.25.
Calculating Cost of Nuts
If nuts cost $9.20 per kilo, to find out how much 2 1/4 kilos would cost, we perform the following calculation:
- Multiply the cost of one kilo of nuts ($9.20) by the number of kilos (2 1/4 or 2.25).
- The calculation is $9.20 * 2.25.
- The total cost for the nuts is $20.70.
Calculating Cost of Milk
If milk costs $0.58 per liter, to find out how much 3 1/2 liters would cost, use this method:
- Multiply the cost of one liter of milk ($0.58) by the number of liters (3 1/2 or 3.5).
- The calculation is $0.58 * 3.5.
- The total cost for the milk is $2.03.
