At one store a trophy costs $12.50. Engraving costs $0.40 per letter. At another store, the same trophy costs $14.75. Engraving costs $0.25 per letter. Write an equation for how many letters the costs will be the same.

• 12.50 + 0.40 = 14.75 + 0.25
• 12.50x + 0.40 = 14.75x + 0.25
• 12.50 + 0.40x = 14.75 + 0.25x
• 0.40x - 12.50 = 0.25x - 14.75
