Maria wants to buy a trophy and engrave her son's name on it. At Trophies Unlimited, trophies cost $12 each and engraving costs 404 per letter, while at Centerpiece Trophies, trophies are $12.50 each and engraving is 30¢ per letter. If Maria's costs would be the same at both stores, which equation shows the number of letters, x, in her son's name? O A. 12(x + 0.4) = 12.5(x + 0.3) O B. 12 + 0.4x = 12.5 + 0.3x C. 0.4 + 12x = 0.3 + 12.5x x x O D. 12 + = 12.5 + 0.4 0.3
