# Bonbons 2

Kilo sweets will cost 260 CZK. The first type has a price per 320 kg, the second type 240 CZK per kg. How many kilos of both kinds of sweets need to prepare a 100 kg mixture ?

Result

x =  25 kg
y =  75 kg

#### Solution:

320x + 240y = 260(x+y)
x+y=100

60x-20y = 0
x+y = 100

x = 25
y = 75
