Question

The cost of a phone has increased by 10% to £352 work out the original price

Answer 1

The answer is £316.80.

This is because you're working out the original price from a percentage increase.

To do this, you do the original price ÷ (1- percentage increase as a decimal).

So it would be 352 ÷ (1 - 0.10) which is 352 ÷ 0.9.

And that equals to £316.80.
