John went to the market with #5.00 she bought twelve 10k stamps eighteen 5k stamps and thirty five 3k stamps how much change did you bring home

Answer 1

John spent:
(12 * 10k) + (18 * 5k) + (35 * 3k) = 120k + 90k + 105k = 315k

With #5.00, John brought:
5 * 100k = 500k

John's change:
500k - 315k = 185k

John brought home #1.85 in change.
