A pack of 8 batteries cost £3.99 how much does each battery cost

0.49875 hope it helps <3

Step-by-step explanation:

3.99 ÷ 8 = 0.49875

Regular selling price (price before discount) 100%.

Price after trade discount of 15% is 85% of regular selling price..

Price after trade discount reduced to 10% is 90% of regular selling price.

By reducing the trade discount from 15% to 10% meant increasing the selling price by 5% of the selling price before applying the trade discount.
