Question

At Superior Engraving, a trophy costs $12.50 and engraving on the trophy costs $0.40 per letter. At another store, Duluth Trophy, the same trophy costs $14.75 and engraving costs $0.25 per letter. How many letters must be engraved for the costs to be the same at both places?

Answer 1

The answer is 15 words

Explanation:

Taking the problem as a algebraic expression, we get

`12.50 + 0.40x = 14.75 + 0.25x`

Now, subtracting 12.50 + 0.25x from both sides, we get

`0.15x = 2.25`

Therefore,

No of words = 2.25/0.15 = 15
