Step-by-step explanation:

Packet of 12 pencils = p
Packet of 30 rulers = r
p = £2.15
r = £6.00
£35 = 4r + xp
£35 = 4(£6.00) + x(£2.15)
£35 = £24 + £2.15x
£11 = £2.15x
x = 5.12
Since she can buy 5.12 packets of pencils, it is equal to 5 packets of pencils.
I would say A. Table of contents
Total area = 12 x 24.6 = 295.2
Area of circle = 3.14 x 3.6² = 40.69
Area of square = 4.2 x 4.2 = 17.64
Square and circle = 40.69 + 17.64 = 58.33
Probability = 58.33/295.2 = 0.1976
Rounded answer = 0.20
