Andy's freight forwarding company charges $19 for plates delivered on time and $16 for plates delivered late. In the month of June, Andy's freight forwarding company collected $2570. For every 14 plates delivered, 11 were delivered on time and 3 were delivered late.

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

	On time	Late	Total
Number	11 u	3 u
Value	19	16
Total Value	209 u	48 u	257 u

(a)
Total amount collected in June
= 209 u + 48 u
= 257 u

257 u = 2570

1 u = 2570 ÷ 257 = 10

Total number of plates delivered late
= 3 u
= 3 x 10
= 30

(b)
Amount that Andy's freight forwarding company collected less from each late delivery of plates
= 19 - 16
= $3

Number of plates delivered late
= 3 u 
= 3 x 10
= 30

Amount that Andy's freight forwarding company collected less from all the late deliveries of plates 
= 30 x 3
= $90

Answer(s): (a) 30; (b) $90
