i have been given this question for my uni course and i have no idea how to do it:
it costs $0.55 for domestic mail within Australia and $2.05 to post a letter to Europe. If i spent $10 to post 10 letters how many of each type did i post?
i need to figure this out using algebra.
i know the answer which you would like could make it easy but no i cant get the computation
