A teacher has been given £35 to spend on pencils and rulers.
SSSSS [86.1K]
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.

Gwar [14]
Given:
V = 5x² + 15x + 2,  the volume
h = 5x,  the height

Let A = the area of the base.
Because V = Ah, therefore
A*(5x) = 5x² + 15x + 2
A =  \frac{5x^{2}+15x+2}{5x}

Answer:
A=x+3+ \frac{2}{5x}
