Let's solve this step by step! ๐
**Step 1:** Understand the problem.
Imagine you have caps and T-shirts. The number of caps to T-shirts is 3 : 2.
**Step 2:** Let the cost of a cap be $x$ dollars.
Then, the cost of a T-shirt is $x + 5.50$ dollars.
**Step 3:** Number of caps = 3 parts, number of T-shirts = 2 parts.
**Step 4:** Total cost of caps = number of caps ร cost per cap = $3x$
**Step 5:** Total cost of T-shirts = number of T-shirts ร cost per T-shirt = $2(x + 5.50) = 2x + 11$
**Step 6:** Mr. Yong spent $259 more on caps than T-shirts:
$$3x = (2x + 11) + 259$$
**Step 7:** Solve the equation:
$$3x = 2x + 11 + 259$$
$$3x = 2x + 270$$
$$3x - 2x = 270$$
$$x = 270$$
**Step 8:** The cost of each cap is $270 dollars! ๐ฏ
**Step 9:** Check total payment:
Cost of caps: $3 imes 270 = 810$
Cost of T-shirts: $2 imes (270 + 5.50) = 2 imes 275.50 = 551$
Sum: $810 + 551 = 1361$ which is less than $2219$, so we must check again.
**Step 10:** Use total money spent $2219$:
Total cost = caps + T-shirts
$$3x + 2(x + 5.50) = 2219$$
$$3x + 2x + 11 = 2219$$
$$5x + 11 = 2219$$
$$5x = 2208$$
$$x = 441.6$$
**Step 11:** So, the cost of each cap is $441.60$ dollars.
**Final answer:**
Cost of each cap = $441.60$
