Step-by-step explanation:
To find the cost of 36 postcards, we need to know the price per postcard. Let's denote the price per postcard as \( P \).
(i) Cost of 36 postcards:
\[ \text{Cost of } 36 \text{ postcards} = 36 \times P \]
(ii) To find out how many postcards we can buy for $225, we'll divide the total amount by the price per postcard:
\[ \text{Number of postcards} = \frac{225}{P} \]
This is the direct method of calculation. Alternatively, if we know the cost of 36 postcards, we can determine the price per postcard and then use it to find out how many postcards can be bought for $225.
Let's say the cost of 36 postcards is $C.
(i) If \( \text{Cost of } 36 \text{ postcards} = C \), then \( P = \frac{C}{36} \).
(ii) Then, the number of postcards that can be bought for $225 is:
\[ \text{Number of postcards} = \frac{225}{P} = \frac{225}{\frac{C}{36}} = \frac{225 \times 36}{C} \]
So, we can either directly find the number of postcards using the price per postcard or find the price per postcard using the cost of 36 postcards and then calculate the number of postcards for $225. Both methods yield the same result.
