Tom's freight forwarding company charges $20 for every crystal bowl delivered on time and $16 for every crystal bowl delivered late. In the month of February, Tom's freight forwarding company collected $1368. For every 12 crystal bowls delivered, 9 were delivered on time and 3 were delivered late.

1. What was the total number of crystal bowls delivered on time?
2. How much less money did Tom's freight forwarding company collect in February due to the late deliveries of the crystal bowls?

	On time	Late	Total
Number	9 u	3 u
Value	20	16
Total Value	180 u	48 u	228 u

(a)
Total amount collected in February
= 180 u + 48 u
= 228 u

228 u = 1368

1 u = 1368 ÷ 228 = 6

Total number of crystal bowls delivered on time
= 9 u
= 9 x 6
= 54

(b)
Amount that Tom's freight forwarding company collected less from each late delivery of crystal bowls
= 20 - 16
= $4

Number of crystal bowls delivered late
= 3 u 
= 3 x 6
= 18

Amount that Tom's freight forwarding company collected less from all the late deliveries of crystal bowls 
= 18 x 4
= $72

Answer(s): (a) 54; (b) $72
