Coffee shop

To the coffee shop brought 2 types of coffee totally 50 kg. The first type was CZK 220 per kilogram, coffee second type 300 CZK per 1 kg. For all the coffee trader earned CZK 12,000. How many kilograms of coffee of first type and how many kilograms of coffee 2nd type brought shop?

Result

x =  37.5 kg
y =  12.5 kg

Solution:

x+y=50
220x + 300 y = 12000

x+y = 50
220x+300y = 12000

x = 752 = 37.5
y = 252 = 12.5
