Archie's freight forwarding company charges $16 for plates delivered on time and $11 for plates delivered late. In the month of September, Archie's freight forwarding company collected $856. For every 14 plates delivered, 12 were delivered on time and 2 were delivered late.

1. What was the total number of plates delivered late?
2. How much less money did Archie's freight forwarding company collect in September due to the late deliveries of the plates?

	On time	Late	Total
Number	12 u	2 u
Value	16	11
Total Value	192 u	22 u	214 u

(a)
Total amount collected in September
= 192 u + 22 u
= 214 u

214 u = 856

1 u = 856 ÷ 214 = 4

Total number of plates delivered late
= 2 u
= 2 x 4
= 8

(b)
Amount that Archie's freight forwarding company collected less from each late delivery of plates
= 16 - 11
= $5

Number of plates delivered late
= 2 u 
= 2 x 4
= 8

Amount that Archie's freight forwarding company collected less from all the late deliveries of plates 
= 8 x 5
= $40

Answer(s): (a) 8; (b) $40
