Hi,

Here is another question that I simply cannot get the right answer (or, at least, the answer marked as correct):

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. $0.5
B. $1.00
C. $1.25
D. $1.50
E. $1.75

I answered B, because that is the value I can compute using the formula given. However, the correction says that the correct answer is C ($1.25). Could anyone please explain me how to get to that value?


Thanks!

Agreed. I don't see how the answer cannot be $1.00. Seems pretty simple. It must be an error.
