Problema Solution
Angie has 57 coins composed of 5 cents and 10 cents. She has 3.85$ total. How many coins of each worth does she have?
Answer provided by our tutors
let 'x' represent the number of 5-cent pieces, then '57-x' represents the number of 10-cent pieces
3.85 = 0.05x + 0.1(57-x)
solving for 'x' we have x=37
57-37 = 20
Angie has 37 5-cent pieces and 20 10-cent pieces
