Sarah took clothes to the cleaners three times last month. First, she brought 3 shirts and 2 pairs of slacks and paid $13.95. Then she brought 7 shirts, 2 pairs of slacks, and 2 sports coats and paid $34 89. Finally, she brought 5 shirts and 1 sports coat and paid $16.44. How much was she charged for each shirt, each pair of slacks, and each sports coat?

How much was she charged for each shirt, each pair of slacks, and each sports coat?

Let:

x shirt
y slacks
z coats

Day 1:  3x + 2y = 13.95
Day 2:  7x + 2y + 2z = 34.89
Day 3: 5x + 1z = 16.44

Solve simultaneouly to get:

x = 1.99,   y = 3.99,   z = 6.49

Hope this helps!
