Nick's freight forwarding company charges $12 for plates delivered on time and $7 for plates delivered late. In the month of April, Nick's freight forwarding company collected $740. For every 14 plates delivered, 10 were delivered on time and 4 were delivered late.

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

	On time	Late	Total
Number	10 u	4 u
Value	12	7
Total Value	120 u	28 u	148 u

(a)
Total amount collected in April
= 120 u + 28 u
= 148 u

148 u = 740

1 u = 740 ÷ 148 = 5

Total number of plates delivered late
= 4 u
= 4 x 5
= 20

(b)
Amount that Nick's freight forwarding company collected less from each late delivery of plates
= 12 - 7
= $5

Number of plates delivered late
= 4 u 
= 4 x 5
= 20

Amount that Nick's freight forwarding company collected less from all the late deliveries of plates 
= 20 x 5
= $100

Answer(s): (a) 20; (b) $100
