Answer:
t=2.5 hours after the freight train leaves the station they will meet.
Step-by-step explanation:
30t = 50 (t - 1)
30t = 50t - 50
30t - 50t = -50

The gross profit margin is calculated using the following rule:
gross profit margin = total profit / total sales
Now, we need to get the values of total profit and total sale:
total profit = <span>9*8-(40+8)=24$
total sales = 9*8 = 72$
Now, we will substitute in the above equation:
gross profit margin = 24/72 = 1/3 = 0.3333334
% = 0.33333334*100 = 33.3334%</span>
