Artem's mother gave him some quarters to spend at school. He contributed some of this money, after he converted it to nickels, to a school project. Knowing this, Artem's mother then gave him 3 times as many dimes as the number of quarters she had given him earlier. Artem then had 75 cents. How much money did Artem's mother give him and how much money did Artem contribute to the school project if he contributed less than $1? What are the possible scenarios?
