Question

When you increase an amount by 120%, to find the new amount in one step, what should you multiply the original amount by?

(appreciate all answers given! also if possible could you tell me how to work it out?)

Answer 1

9514 1404 393

Answer:

multiply by 2.2

Explanation:

If you start with an amount x, and add to it 120% of x, you have ...

x(100%) + x(120%)

= x(220%) = 2.20x

You can find the new amount by multiplying by 2.2.
