Final answer:
To calculate the total cost of the engagement ring including VAT at 17%, first find the VAT by multiplying £420 by 0.17 to get £71.40. Then, add this VAT to the original cost to arrive at the total cost of £491.40.
Step-by-step explanation:
Wayne bought an engagement ring for Tracy. The total cost of the ring was £420 plus VAT at 17%. To calculate the total cost including VAT, you can use the following steps:
- Find the amount of VAT by calculating 17% of £420.
- Add the VAT to the original cost to get the total cost.
To find 17% of £420, multiply £420 by 0.17:
£420 × 0.17 = £71.40
Now, add the VAT to the original cost:
£420 + £71.40 = £491.40
So, the total cost of the engagement ring including VAT is £491.40.
