Sam is 5
Tom is 3 times older so 3*5=15
The difference between them is 15-5=10 years
When Sam is 20 we add the difference 20+10=30, and we have Tom's age :)

What’s the answer for it

Answer: Part 1: 111.24

Part 2: 9.27

Part 3: 54 minutes

Step-by-step explanation:

Part 1: Since you already know that the total bill increases by 3%, you just have to find 103% of 180.

1.03*108= 111.24; your answer would be 111.24 pounds

Part 2: Since you already know yearly, 111.24 divided by 12= 9.27 per month

Part 3: First find 73% of 200 which is 146. Then subtract that from 200 which is 54. So you have 54 minutes left.
