Answer:
£69
Step-by-step explanation:
Given information:
- Cost of dress = £50
- Cost of shoes = £43
- Discount offer: Buy a dress and shoes together and get 1/3 off the price.
- Shipping & handling charge = £7 (added after the discount is applied)
Cost of buying a dress and shoes:
⇒ £50 + £43 = £93
Discount:
⇒ 1/3 of £93 = 1/3 × 93 = £31
Cost of goods after discount is applied:
⇒ £93 - £31 = £62
Addition of shipping and handling:
⇒ £62 + £7 = £69
Therefore, Ruth will pay £69 if she buys a dress and shoes.
