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 120 % 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 150 % more than 40
