Answer: $11.80 for another 4 panes of glass.
Step-by-step explanation: We know that 9 panes of glass cost $26.55, but we should first find how many dollars would it cost per pane of glass, or 1.
So, we can divide 26.55 by 9 to find the price per 1 pan of glass.
26.55/9 = 2.95, or $2.95 per pane of glass.
Now, we want to know how much it will cost for 4 panes of glass. Simply multiply 2.95 by 4.
2.95 x 4 = 11.8, or $11.80 for another 4 panes of glass.
Answer: 
Step-by-step explanation:
1. To find the equation asked, you must add the times:

Where
is the time takes Lilly in her path to work and
is the time takes Lilly in her path to home.
2. You must use the following formula of speed and solve for the time

Where n is the distance, V is the speed and t is the time.
3. You know that Lilly takes a train each day to work that averages 35 miles per hour, then, you can write the following expression:

4. And her train ride follows the same path at 45 miles per hour:

5. Then, you obtain the following equation:
