I:
s=5
p=9.50+0.25(5-1)=10.50
II:
s=1
p=9.50+0.25(1-1)=9.50
10.50-9.50=1

of course it is b. you can use a short cut. just take the second part of the equation. no need to add to 9.5.
good luck

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
