Final answer:
George buys food for £16.55 and pays with two notes and four coins. The correct combination that equals the exact amount is a £10 note, a £5 note, and coins of £1, 50p, 5p, and 1p, which is Option A.
Step-by-step explanation:
The student is asking about a scenario where George buys food with a total cost of £16.55 and pays with a combination of two notes and four coins. We need to determine which combination of notes and coins he used. We can begin by identifying the largest possible note that is less than the total amount, which is a £10 note. This is feasible because George uses exactly two notes, and we know that there's no £20 note mentioned that would add up to less than £16.55. Now, subtracting £10 from £16.55, we have £6.55 left to cover with one more note and four coins. The next highest value note he could use is the £5 note, subtracting this we're left with £1.55 to be paid in coins.
At this point, we would use the largest value coin which is £1 and subtract it from £1.55, leaving us with 55 pence. This can be obtained using a 50p coin, a 5p coin, and a 1p coin. Keep in mind we must use exactly four coins. Thus, we can conclude that George paid with: £10 note, £5 note, and four coins consisting of £1, 50p, 5p, and 1p. Therefore, the correct answer is Option A: £10, £5, £1, £0.50, £0.05, and £0.01.
