use elimination method in Algebra
Let x be the transported
Let y be the dropped
then make the equation
5x + 2y = 11
8x + 5y = 5
----------------
-8 (5x + 2y = 11)
+5 (8x + 5y = 5)
--------------------
-40x - 16y = -88
+40x + 25y = +25
____________________
+ 9y = -63
----------- divide by 9
9 9
____________________
y = -7
so 7 points were deducted
