Question 5 3.2 meters of electrical cable and 0.6  of copper wire costs total £4.07
electrical cable costs 85p per meter
how much does copper wire cost per meter
show clearly all your workings

85p x3 meters = £2.55
100÷85= .85 x 20 = 17 p
= £2.55 + 17p = £2.72  for 3.2 meters electrical cable
£4.07 -£2.72 =£1.35
= ÷6 into £1.35   = 22.5p  per meter copper wire
