-18x+162-x+9=0
-19x+171=0
-19x=0-171
-19x=-171
19x=171
x=171/19

Answer:
A. 120%
B. 150%
Step-by-step explanation:
a. Let 'a' represent the percentage of interest.
600 = a% × 500
600/500 = a/100 . . . . . . . % means /100
100(6/5) = a = 120
600 is <u> 120 </u>% of 500
__
b. Let 'b' represent the percentage of interest. The given statement means ...
100 = 40 + b% × 40
100 = 40(1 +b/100) . . . . . factor out 40, use /100 for %
2.50 = 1 +b/100 . . . . . . . divide by 40
1.50 = b/100 . . . . . . . . . . subtract 1
150 = b . . . . . . . . . . . . . . multiply by 100
100 is <u> 150 </u>% more than 40
