Question 8 - Answer

1 set = 47 delivered parcels + 3 late parcels

        = 47 x 15 - 3 x 5

        = 705 - 15

        = 690

Number of set = 35,880/690 = 52 set

Number of late parcels = 52 x 3 = 156

(a) There were 156 parcels delivered late in January.


156 x ( 5 + 15 ) = 3120

(b) $3120 was lost because of late delivery.
