Problema Solution
susan paid for her library fine with 23 coins consisting of nickles and dimes. if the fine was $2.05 how many coins were nickles?
Answer provided by our tutors
let 'x' represent the number of nickles, then '23-x' represents the number of dimes and we have:
2.05 = 0.05x + 0.10(23-x)
solving for 'x' we have x=5
23-5=18
susan paid her fine with 5 nickles and 18 dimes
