After paying $5.12 for a salad, Norachai has $27.10. How much money did he have before buying the salad? (What is the unknown and what would be the equation?)

• n=amount of $ he had at 1st; n + $5.12 = $27.10
• n=amount of $ he had at 1st; n - $5.12 = $27.10
• n=cost of the salad; n - $5.12 = $27.10
• n=amount of $ he had at 1st; $5.12 - n = $27.10
