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?
