Answer:
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

Answer:
1. 30
2. 13 meters
Step-by-step explanation:
Let the number be x.
x - (10% of x) = 27.
x - 0.1x = 27
0.9x = 27.
x = 27/0.9
x = 30
The number is 30
Second question:
Length = 2x - 3
Width = x
Perimeter = 72
Perimeter = 2(l + w)
= 2(2x - 3 + x) = 72
4x - 6 + 2x = 72
6x = 72 + 6
6x = 78
w = 78/6 = 13
The width is 13 meters
