I REALLY NEED HELP WITH THIS QUESTION!!!!

Jim took clothes to the cleaners three times last month. First, he brought 2 shirts and 2 pairs of slacks and paid $17.96. Then he brought 6 shirts, 3 pairs of slacks, and 2 sports coats, and paid $49.89. Finally, he brought 5 shirts and 1 sports coat and paid $21.94. How much was he charged for each shirt, each pair of slacks, and each sports coat?
