Problema Solution
Two boys sold 350 stamps from their collections.They sold some for $.30 each and others for $.50 each and received in all $116.00.How many stamps of each kind did they sell
Answer provided by our tutors
let 'x' represent the number of stamps sold for $0.30, then '350-x' represents the number of stamps sold for $0.50
116.00 = 0.30x + 0.50(350-x)
solving for 'x' we have x=295
350-295 = 55
55 stamps were sold for $0.50, 295 stamps were sold for $0.30
