p=9.50+0.25(1-1)=9.50
10.50-9.50=1

salary of grade 5 ==> p=9.50 + 0.25(5 – 1) 9.50+.25*4=10.50
salary of grade 1 ==> p=9.50 + 0.25(1 – 1) 9.50
so answer is B only

It can't be C, answer is 1.0

\(\Delta p = \Delta s * 0.25 = 4*0.25\)

A. $0.50
B. $1.00
C. $1.25
D. $1.50
E. $1.75


\(p_5 = 9.50 + 0.25(5 – 1) => 10.50
p_1 = 9.50 + 0.25(1 – 1) => 9.50\)

So, \(p_5 - p_1 = 1\)

Hence, aswer will definitely be (B) $ 1.00

E. $1.75


We are given that each employee receives an hourly wage p, in dollars, determined by the formula p = 9.50 + 0.25(s – 1), in which s = the salary grade. We need to determine how many more dollars per hour an employee with a salary grade of 5 receives than does an employee with a salary grade of 1. Thus:

9.50 + 0.25(5 – 1) - [9.50 + 0.25(1 – 1)]

9.50 + 0.25(4) - [9.50 + 0.25(0)]

9.50 + 0.25(4) - 9.50

0.25 x 4 = $1.00

Answer: B
