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?

Result

a =  8 kg
b =  4 kg

Solution:

a+b=12
180a + 240b = 200*12

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

a = 8
b = 4
