Let’s solve each problem one by one. We’ll calculate the extra amount (tax, fee, discount, tip) and then add or subtract it from the original price to get the final answer.

1.) New speakers: $154.90 + 6% tax
First, find 6% of $154.90:
→ 6% = 0.06

Add tax to original price:
→ 154.90 + 9.29 =
$164.19

2.) Shoes: $49.50 + 4% tax
Find 4% of $49.50:

3.) Scooter: $200.00 + 5% delivery fee
5% of 200 = 0.05 × 200 = 10

4.) Book: $19.50 + 60% if signed
60% of 19.50 = 0.60 × 19.50 = 11.70

6.) Laptop: $824.90 + 10% tax
10% of 824.90 = 0.10 × 824.90 = 82.49

7.) Golf club: $159.50 - 60% discount
60% of 159.50 = 0.60 × 159.50 = 95.70
