Tea mixture

Of the two sort of tea at a price of 180 CZK/kg and 240 CZK/kg we make a mixture 12 kg that should be prepared at a price of 200 CZK / kg. How many kilos of each sort of tea will we need to be mixed?

Correct result:

a =  8 kg
b =  4 kg


180a + 240b = 200•12

180•a + 240•b = 200•12

a+b = 12
180a+240b = 2400

a = 8
b = 4
