Question

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. How many letters must be engraved for the costs to be the same?

Answer 1

Answer: 15 letters.

Explanation:

When p is the number of letters being engraved:

12.5 + .4p = 14.75 + .25p

-12.5 -12.5

.4p = 2.25 + .25p

-.25p -.25p

.15p = 2.25

/.15 /.15

p = 15

There would need to be 15 letters engraved for the cost of the trophies to be the same. Hope this helps!
