A pair of shoes is in a ‘35% off’ sale. The recommended retail price (RRP) is £86. How much do the shoes cost in the sale?

9966 [12]

Answer:

Without tax the shoes would cost £55.9.

Step-by-step explanation:

To get this you take the £86 and multiply it by 0.65 because with the 35% sale you are paying for 65% of the item. You get this number by subtracting 35 from 100 and convert it into a decimal.
