She would save £5
Step-by-step explanation:
→ First work out the cost of items for one student. Work out cost of the photocopying
40 × £0.02 = £0.80
→ Add the cost of the one folder
£0.80 + £0.70 = £1.50
⇒ Now we know £1.50 is the amount of money it costs for one student, we multiply that by 120 because there are 120 pupils
£1.50 × 120 = £180
→ £180 is the total cost and now we minus that from the online price of £175
£180 - £175 = £5
