Answer: 25%
Step-by-step explanation:
From the question, we are informed that Allison earned $200 the first month she worked and $250 the second month she worked.
The percentage increase in her salary will be calculated as:
= Salary Increase / Old salary × 100
= (250 - 200) / 200 × 100
= 50/200 × 100
= 1/4 × 100
= 25%
The percentage increase is 25%

Answer:
None
Step-by-step explanation:
For option A
3-2r/4=10 and combining like terms and re-arranging we obtain
-2r/4=10-3
-2r/4=7
r=7*4/-2=-14
For option B
3/4-2r=10 then combining like terms and re-arranging
-2r=10-3/4
-2r=9 1/4
r=(9 1/4)/-2=-4.625
For option C
3(r-4)=10 dividing both sides by three first
r-4=10/3
r=10/3+4= 7 1/3
For option D
3-r/4=10
-r/4=10-3
-r/4=7
r=7*-4=-28
Therefore, none of the options yields r=-17
