Suri makes $15 per hour and gets a weekly bonus of $25. Juan makes $14 per hour and gets a weekly bonus of $50. Is it possible for Suri and Juan to make the same amount of wages, y, by working the same number of hours, x, in one week?

• Yes, because the slopes of the equations are different so the system of equations will have one solution.

• No, because the slopes of the equations are different so the system of equations will have no solutions.

• Yes, because the slopes of the equations are the same so the system of equations will have infinitely many solutions.

• No, because the slopes of the equations are the same so the system of equations will have no solutions.
