To calculate the cost of 7 candies and the cost of 7 gingerbreads, we can use the information provided in the search results.

The cost of 1 candy is represented by the equation $TU=4xy$, where $X$ and $Y$ are variables. The equation states that the cost of 1 candy is 4 times the product of $X$ and $Y$. Additionally, it's mentioned that $X$ is 400 and $Y$ is 300, which gives us the cost of 1 candy as 1200.

The cost of 1 gingerbread is 200.

Now, we can calculate the total cost of 7 candies and 7 gingerbreads.

Cost of 7 candies: Using the given equation, the cost of 7 candies is calculated as 7 multiplied by 1200, which equals 8400.

Cost of 7 gingerbreads: The cost of 7 gingerbreads is calculated as 7 multiplied by 200, which equals 1400.
