Harry's freight forwarding company charges $16 for mirrors delivered on time and $12 for mirrors delivered late. In the month of January, Harry's freight forwarding company collected $1800. For every 13 mirrors delivered, 11 were delivered on time and 2 were delivered late.

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

	On time	Late	Total
Number	11 u	2 u
Value	16	12
Total Value	176 u	24 u	200 u

(a)
Total amount collected in January
= 176 u + 24 u
= 200 u

200 u = 1800

1 u = 1800 ÷ 200 = 9

Total number of mirrors delivered late
= 2 u
= 2 x 9
= 18

(b)
Amount that Harry's freight forwarding company collected less from each late delivery of mirrors
= 16 - 12
= $4

Number of mirrors delivered late
= 2 u 
= 2 x 9
= 18

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

Answer(s): (a) 18; (b) $72
