Question

250% increase of 28,000?

Answer 1

In math "of" means multiply (x). So 250% increase of 28,000 means

250% x 28,000 + 28,000 (we add 28000 because it's an increase so we have to add it to the original amount).

250% x 28000 =
2.5 x 28000 = 70,000

Now add it back to the original 28,000

70,000 + 28,000 = 98,000

Answer 2

250% can be converted into a fraction 250/100 or into a decimal 2.50.
so 250% of 28,000 is 2.50 times 28,000 which is 70,000.
28,000 is increased by 70,000 to 98,000
