Answer:
Step-by-step explanation:
You could do this in one step, but I think you should do it the long way until you discover the short way yourself.
18/100 x = 24 Multiply both sides by 100
18x = 24 * 100
18x = 2400 Divide by 18
x = 2400/18
x = 133.3333
Now what you need to do is take 3% of 133.3333
3/100 * 133.3333 Multiply by 3
400/100 = 4
