A car wash charges two prices depending on the size of the vehicle. The table shows the number of cars and the number of SUVs washed in the past 3 hours. The total earnings for hours 1 and 2 are given. Each car costs the same price, and each SUV costs the same price. The system of equations can be used to represent the situation.
In the system of equations, x represents the, _and y represents the_.
If the system of equations is graphed in a coordinate plane, the coordinates (x, y) of the intersection of the two lines are_.
The total cost of 1 car and 1 SUV is $_.
The total earnings for hour 3 are $_.
The missing part of the picture is:
4x + 2y = 84
3x + 5y = 126
