Alex was charged$___ for each shirt,$____ for wach pair os slacks, and $___ for each sports coat.

Answer 1

Let shirt be x, pair of os slack be y and sports coat be z

Then

3x+2y = 11.45. (1)

6x+2y+2z =28.90.    ( 2)

4x+2z =18.94. ( 3)

X = 11.45-2y divided by 3

Z = 18.94-4x divided by 2

Putting the value of both in equation (2)
