Let's solve this problem step by step:

Step 1: Understand the problem
The problem states that 3 red bean buns cost the same as 1 box of sweets. Lily bought 12 red bean buns and 3 boxes of sweets for $42. We need to find the cost of 1 box of sweets.

Step 2: Set up the equations
Let's denote the cost of 1 red bean bun as 'b' and the cost of 1 box of sweets as 's'. From the problem, we know that 3b = s (since 3 red bean buns cost the same as 1 box of sweets). We also know that 12b + 3s = $42 (since Lily bought 12 red bean buns and 3 boxes of sweets for $42).

Step 3: Solve the equations
We can substitute the first equation into the second to get 12b + 3(3b) = $42, which simplifies to 21b = $42. Solving for 'b', we get b = $42 / 21 = $2. This means that each red bean bun costs $2.

Since 3 red bean buns cost the same as 1 box of sweets, we can find the cost of 1 box of sweets by multiplying the cost of 1 red bean bun by 3. So, s = 3b = 3 * $2 = $6.

So, 1 box of sweets costs $6.
