Final answer:
When paying £5 for an item that costs £2.4, subtract the cost from the amount tendered to find that the change due is £2.6.
Step-by-step explanation:
If a student spends £2.4 on food and pays with a £5 note, the calculation of change involves subtracting the amount spent from the amount paid with. Here is a step-by-step calculation to determine your change:
- Take the value of the money you paid with, which is £5.
- Subtract the amount you spent on food, which is £2.4, from the £5 note.
- Calculate the difference: £5 - £2.4 = £2.6
Hence, you should receive £2.6 in change after the transaction.
