5. a packet of razors and a bar of soap cost £5.50. if the soap costs £2.50 less than the razors, find the cost of each.

Let the cost of soap be x,
cost of razors = x + 2.5
total cost = 2x + 2.5
2x + 2.5 = 5.5
2x = 3
x = 1.5
cost of razors = 1.5 + 2.5
= 4

The cost of the packet of razors and bar of soap is £4.00 and £1.50 respectively.
