Let's solve the problem step by step.

### Part (a) 
The original price of the music stand is **£30**, and the shop is offering a 10% discount.

1. To find the discount, calculate **10% of £30**:
   \[
   0.10 \times 30 = 3
   \]

2. Subtract this discount from the original price to get the sale price:
   \[
   30 - 3 = 27
   \]
   So, the music stand costs **£27** during the sale.

### Part (b) 
Now, the shop offers a **10% discount** on the sale price of **£27** during a clearance event.

1. To find the discount, calculate **10% of £27**:
   \[
   0.10 \times 27 = 2.70
   \]

2. Subtract this discount from the sale price to get the final price during the clearance event:
   \[
   27 - 2.70 = 24.30
   \]
   So, the music stand costs **£24.30** during the clearance event.

Would you like further details or have any questions? Here are 5 related questions for practice:

1. If the shop had offered a 15% discount in the first sale, how much would the music stand cost?
2. What if, after the clearance event, they offered another 5% discount on the final price? What would be the new cost?
3. How much total percentage discount has been applied after both sales?
4. How much money has the shop discounted in total from the original price to the clearance price?
5. If the original price was £40 instead of £30, how much would the stand cost after both discounts?

**Tip:** Always remember that consecutive percentage discounts are applied to the new price each time, not to the original price!

The original price of a music stand was £30.
(a) A shop holds a sale and reduces the price of everything by 10%. How much does the music stand cost in the sale?
(b) One week later, they hold a clearance event and take 10% off their sale prices. How much does the music stand cost during the clearance event?
