Answer:
Form an equation:
let x be the price of a shirt
Then, the price of a sweater would be x - 5
So you would have:
4(x - 5) + 3x = 200
simplify
4x - 20 + 3x = 200
7x - 20 = 200
add 20 to both sides
7x = 220
divide both sides by 7
x = about 31.43
That means the cost of the sweater would be 31.43 - 5 = 26.43

10% = £1.32
5% = £0.66
so you would add 10% and 5% together which gives you 15% and 15% is £1.98
and then you could to £13.20 - £1.98 which equals to £11.22
