Answer:
B. 30
Step-by-step explanation:
Let x represent the number. Then we have ...
96 = 0.80x
Dividing by 0.80 gives ...
x = 96/0.80 = 120
Then 25% of the number is ...
0.25 × 120 = 30
___
If you like, you can write the proportion ...
x/96 = 25%/80% . . . . . . . where x represents 25% of the number
x = 96×(25/80) = 30 . . . . this is the 25% value that we want
