Three lorries droved bricks. One drove n bricks at once, second m less bricks than the first and third 300 bricks more the first lorry. The first lorry went 4 times a day the largest went 3 times a day and the smallest 5 times a day.

How many bricks brought:

a / all lorries in one day.
b / all lorries per week / Sunday don't worked /?

Result

a = (Correct answer is: 12n-5m+900) b = (Correct answer is: 72n-30m+5400) #### Solution:  Leave us a comment of example and its solution (i.e. if it is still somewhat unclear...):
