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 35 kg mixture ?

Correct answer:

x =  8.75 kg
y =  26.25 kg

Step-by-step explanation:


320x + 240y = 260(x+y); x+y=35

320•x + 240•y = 260•(x+y)
x+y=35

60x-20y = 0
x+y = 35

x = 35/4 = 8.75
y = 105/4 = 26.25
