A farmer has a vat of 3%-fat milk and a vat of 27%-fat cream. How much of each should he use to mix 30 gallons of 4%-fat milk?

Is there more than one way to solve this? (Mine looks clunky to me.)
У фермера есть молоко 3% жирности и сливки 27% жирности. Сколько того и другого ему надо смешать, чтобы получить 30 литров 4% молока?

Интересно, сколько есть способов решения? (Мой кажется мне неуклюжим.)

In the US Algebra begins in 9th grade, so 9 for regular track, 10 - for slower track.
