If you had thirty cents you could order a bowl of soto in the past

I remember, when as a young boy growing up in the seventies I can order a bowl of mee soto ( it is a soup mainly compose of broth, noodle, meats and vegetables) from my school tuck shop for thirty cents only, that was the buying power of thirty cents in 1970. In addition all sweet candies are priced at two for five cents. But these days thirty cents does not buy much.
