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 ?

Correct result:

x =  25 kg
y =  75 kg

Solution:


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

320•x + 240•y = 260•(x+y)
x+y=100

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

x = 25
y = 75
