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

It can't be C, answer is 1.0

$$\Delta p = \Delta s * 0.25 = 4*0.25$$

Salary grade of 5 is $$p(5)=9.50+0.25(5–1)=9.50+0.25*4$$;

Salary grade of 1 is $$p(1)=9.50 + 0.25(1–1)=9.50$$;

$$p(5)-p(1)=9.50+0.25*4-9.50=1$$.

A. $0.50 B.$1.00
C. $1.25 D.$1.50
E. $1.75 p = 9.50 + 0.25(s – 1). Hourly wage (p) if S=1 --> 9.50 + 0.25(1 – 1) = 9.5 Hourly wage (p) if S=5 --> 9.50 + 0.25(5 – 1) = 9.5 + 0.25 x 4 = 9.5 + 1.00 So the answer has to be B. Kindly confirm the OA because OA can not be C. Emma _________________ Kudos will encourage many others, like me. Good Questions also deserve few KUDOS.

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

So, $$p_5 - p_1 = 1$$

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 = $1.00 Answer: B _________________ Scott Woodbury-Stewart Founder and CEO GMAT Quant Self-Study Course 500+ lessons 3000+ practice problems 800+ HD solutions Kudos [?]: 837 [0], given: 2 Senior Manager Joined: 25 Mar 2013 Posts: 275 Kudos [?]: 33 [0], given: 101 Location: United States Concentration: Entrepreneurship, Marketing GPA: 3.5 Re: At a certain company, each employee has a salary grade s tha [#permalink] ### Show Tags 12 Feb 2017, 16:33 How many more dollars = ? for grade 5 than grade 1 ? Just substitute in equation S = Grade 1 to Grade 5 P = 9.50$ + 0.25$(S-1) P = 9.50$ + 0.25(5-1) = 10.50$P = 9.50$ + 0.25(1-1) = 9.50$Difference 1$
