At a certain company, each employee has a salary grade s that is at least 1 and at most 5. Each employee receives an hourly wage p, in dollars, determined by the formula p = 9.50 + 0.25(s – 1).

A) $0.75  B) $1.00  C) $1.25  D) $1.50  E) $1.75
Salary grade of 4 is p(4)=9.50+0.25(4–1)=9.50+0.25*3;   Salary grade of 1 is p(1)=9.50 + 0.25(1–1)=9.50;   p(4)-p(1)=9.50+0.25*4-9.50=0.75.   $0.75nswer: $0.75.
