Answer 1

To calculate the average price paid for a steel plate over the period of January-March, add the total prices for each month and divide by the total number of steel plates bought. The average price is N$3.06. The total price paid for the steel plates is N$1,378.20.

Step-by-step explanation:

To calculate the average price paid for a steel plate over the period of January-March, you need to find the total price paid and divide it by the total number of steel plates bought. Here are the steps:

1. Calculate the total price paid for each month: January: 250 plates x N$2.54 = N$635, February: 110 plates x N$3.59 = N$394.90, March: 90 plates x N$3.87 = N$348.30
2. Add the total prices for each month: N$635 + N$394.90 + N$348.30 = N$1,378.20
3. Calculate the total number of steel plates bought: 250 + 110 + 90 = 450 plates
4. Divide the total price paid by the total number of steel plates: N$1,378.20 / 450 = N$3.06

The average price paid for a steel plate over the period of January-March is N$3.06.

To calculate the total price paid for the steel plates, simply add up the total prices for each month: N$635 + N$394.90 + N$348.30 = N$1,378.20.
