Question

Gerallt used his 20% off voucher to buy tickets. He paid £120 for tickets using the voucher. How much would these tickets have cost Gerallt without a voucher?

Answer 1

The tickets would have cost Gerallt £150 without the voucher.

Explanation:

Set up the equation: 80% of x = £120

Divide both sides of the equation by 80% (which is equivalent to dividing by 0.8):

x = £120 / 0.8

Simplify the right side of the equation:

x = £150
