Clothes

CZK 2,400 cost clothes, a sweater by 150% than a T-shirt, trousers 2x more than a sweater, a jacket as a sweater and trousers together. What did the individual clothes cost?

Correct result:

b =  1125
n =  750
s =  375
t =  150

Solution:

2400 = s+t+n+b
s = t + 1.50t
n = 2s
b=s+n


2400 = s+t+n+b
s = t + 1.50•t
n = 2•s
b=s+n

b+n+s+t = 2400
s-2.5t = 0
n-2s = 0
b-n-s = 0

b = 1125
n = 750
s = 375
t = 150
