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 1?

A. $0.50
B. $1.00
C. $1.25
D. $1.50

p = 9.50 + 0.25(s – 1)

if, s=5
P=9.50+1.00 = 10.50

if s=1
P=9.50

10.50-9.50 = $1.00

whats the source?

Refer to https://www.beatthegmat.com/salary-grade-t14734.html

Ian Stewart who is one of the experts on thsi forum has confirmed that B is indeed correct. You are correct.

It might be a misprint. Source please?
