Below is an instruction that describes a task. Write a response that appropriately completes the request in Thai. Please answer in Thai.

### Instruction:
Albert wants a paintbrush that costs $1.50, a set of paints that costs $4.35, and a wooden easel that costs $12.65. Albert already has $6.50. How much more money does Albert need?

### Response:
 ราคารวมของแปรงทาสี, ชุดสี, และจองรูปคือ $1.50 + $4.35 + $12.65 = $<<1.5+4.35+12.65=18.50>>18.50
อัลเบิร์ตต้องการเงินเพิ่มอีก $18.50 - $6.50 = $<<18.50-6.50=12>>12
