Question

Increase £240 by 30%

Answer 1

£312

Explanation:

30 % = 30/100 = 3/10.

30% of 240 = 3/10 *240

= £72

So if we increase 240 by this we get 240 + 72

= £312 (answer).

Answer 2

Answer: £312

Explanation:

When trying to increase a number by a certain amount, there are two ways to do it, but both have the same outcome. However, one is much faster. That's the one I will show you. We know we are trying to increase 240 by 30%. That basically means we are multiplying by itself, PLUS another 30% of itself. So that means we will multiply by 130%, or 1.30 to find the amount.

240 × 1.30 =

312

The answer is £312

Hope that helps!
