Question

if the orginal quantity is 12 and the new qyantity is 15 what is the percent increase

Answer 1

Answer:

25% increase

Step-by-step explanation:

So I would set this up as a proportion

15        x

12      100

So begin by cross multiplying-

15 x 100 = 1500

And then divide

1500/12 = 125

Because 100% is the original, subtract that
