Translate the word phrase into a variable expression1. 15 less than a number.

Lets just say for funzies that "a number" is represented by a variable, say n. We need something that is 15 less than n. This means that subtraction is necessary. The equation representing 15 less than a number is n-15

I would be n-15 because when is says less then a number it means something or (n) or (x) - what ever number you need in this case (15)

Ithink ghe answer to this question is b just trying to others
