Vincent's freight forwarding company charges $16 for mirrors delivered on time and $12 for mirrors delivered late. In the month of March, Vincent's freight forwarding company collected $2928. For every 16 mirrors delivered, 13 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 Vincent's freight forwarding company collect in March due to the late deliveries of the mirrors?

	On time	Late	Total
Number	13 u	3 u
Value	16	12
Total Value	208 u	36 u	244 u

(a)
Total amount collected in March
= 208 u + 36 u
= 244 u

244 u = 2928

1 u = 2928 ÷ 244 = 12

Total number of mirrors delivered late
= 3 u
= 3 x 12
= 36

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

Number of mirrors delivered late
= 3 u 
= 3 x 12
= 36

Amount that Vincent's freight forwarding company collected less from all the late deliveries of mirrors 
= 36 x 4
= $144

Answer(s): (a) 36; (b) $144
