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). An employee with a salary grade of 5 receives how many more dollars per hour than an employee with a salary grade of 2?  Choose the correct choice from the following options:
A) $0.50
B) $0.75
C) $1.25
D) $1.50
E) $1.75
Salary grade of 5 is p(5)=9.50+0.25(5–1)=9.50+0.25*4;   Salary grade of 2 is p(2)=9.50 + 0.25(2–1)=9.50+0.25;   p(5)-p(2)=9.50+0.25*4-9.50-0.25=0.75.   Answer: $0.75.
