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.
An easier way to write this would be -9-15, which we can solve just by counting backwards for 15 numbers from -9. When we do this, we can see that his expression is equal to -24.
