Answer to the question is: I
Cost of 192 tile at $0.80 = 192 x .80 = $153.60
Change due from $200.00 =$200 - $153.60= $46.40
If you would like to solve the system of linear equations, you can do this using the following steps:
2x - y = -1 ... y = 2x + 1
2x + y = -7 ... y = -7 - 2x
The correct result would be: y = 2x + 1, <span>2x + y = -7.</span>
