Lowell has a credit card that uses the adjusted balance method. for the first
10 days of one of his 30-day billing cycles, his balance was $1360. he then
made a purchase for $470, so his balance jumped to $1830, and it remained
that amount for the next 10 days. lowell then made a payment of $740, so
his balance for the last 10 days of the billing cycle was $1090. if his credit

amount lowell was charged in interest for the billing cycle?
