Riordan's freight forwarding company charges $14 for mirrors delivered on time and $12 for mirrors delivered late. In the month of August, Riordan's freight forwarding company collected $1458. For every 12 mirrors delivered, 9 were delivered on time and 3 were delivered late.

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

	On time	Late	Total
Number	9 u	3 u
Value	14	12
Total Value	126 u	36 u	162 u

(a)
Total amount collected in August
= 126 u + 36 u
= 162 u

162 u = 1458

1 u = 1458 ÷ 162 = 9

Total number of mirrors delivered late
= 3 u
= 3 x 9
= 27

(b)
Amount that Riordan's freight forwarding company collected less from each late delivery of mirrors
= 14 - 12
= $2

Number of mirrors delivered late
= 3 u 
= 3 x 9
= 27

Amount that Riordan's freight forwarding company collected less from all the late deliveries of mirrors 
= 27 x 2
= $54

Answer(s): (a) 27; (b) $54
