Hint:

For out the discount using simple percentages.

To work out 30%, first find 10% (÷ 10) then multiply by 3.

To work out 25%, you can divide by 4, as it is the same as 1/4. Or you can work out 10%, divide 10% by 2 to have 5%, the add 2 x 10% and 5%

Don't forget to subtract the discount from the minimum amount.

Answers:

30% of £80:

10% is 8

so 30% is 24

80 - 24 = £56

25% of 70:

70 ÷ 4 = 17.5

70 - 17.5 = £52.50

Townsman is cheapest.
