Mike took clothes to the cleaners three times last month. First, brought 4 shirts and of slacks and paid $11.45. Then brought 7 shirts, 2 pairs of slacks, and 2 sports and paid $35.39. Finally, brought 5 shirts and 2 sports and paid $21.43 . How much was charged for each shirt, each pair of slacks, and each sports coat?
Let the cost of cleaning 1 shirt =S
Let the cost of cleaning 1 pair of slacks =P
let the price of cleaning 1 sports coat = C
4S + P =11.45..................(1)
7S + 2P + 2C =35.39.......(2)
5S + 2C = 21.43...............(3)
Now, you have 3 simultaneous equations. Can you solve them?
