Lenka and money

When Lenka bought pants from 1/3 of her savings shirt from 1/5 and 1/8 spent at the hairdresser, she is left 328 Kč.

How much money was saved? How much hairdresser cost?

Result

x =  960
k =  120

Solution:


x - 1/3 x - 1/5 x - k = 328
k = 1/8 x

-15k+7x = 4920
8k-x = 0

k = 120
x = 960
