1. Problem Description

Lewis has £2 in coins. He uses five coins with values 10p, 50p, 20p, 20p, and 10p to make a call. How much money has he got left?

2. Solution Steps

First, convert £2 into pence.

£1 = 100p, therefore £2 = 2 * 100p = 200p.

Next, calculate the total value of the five coins used for the call.

Total value = 10p + 50p + 20p + 20p + 10p = 110p.

Then, subtract the total value of the coins used from the initial amount.

Remaining money = 200p - 110p = 90p.

3. Final Answer

90p
