Question 1016081: A person opens his wallet and finds that all the bills are $1 bills, $5 bills, or $10 bills. There are 38 bills in this persons wallet. There are 3 more $5 than $1. If the total amount of bills is $239, how many $10 bills does this person have? Answer by josgarithmetic(39625) (Show Source):

to find the value for y.
