Hi! I am new here and I have a question that I don’t know how to answer. Please help!
Lisa has some 50 cent coins and 20 cent coins in the ratio if 2:3. She exchanged six 50cent coins for 20 cent coins. If the ratio of 50cents coins to 20cents coind became 2:5, find the amount of money Lisa had.
I would be grateful if you could provide me with a solution or some steps. Thanks!
