Billy's freight forwarding company charges $14 for every mirror delivered on time and $11 for every mirror delivered late. In the month of May, Billy's freight forwarding company collected $1472. For every 14 mirrors delivered, 10 were delivered on time and 4 were delivered late.

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

	On time	Late	Total
Number	10 u	4 u
Value	14	11
Total Value	140 u	44 u	184 u

(a)
Total amount collected in May
= 140 u + 44 u
= 184 u

184 u = 1472

1 u = 1472 ÷ 184 = 8

Total number of mirrors delivered on time
= 10 u
= 10 x 8
= 80

(b)
Amount that Billy's freight forwarding company collected less from each late delivery of mirrors
= 14 - 11
= $3

Number of mirrors delivered late
= 4 u 
= 4 x 8
= 32

Amount that Billy's freight forwarding company collected less from all the late deliveries of mirrors 
= 32 x 3
= $96

Answer(s): (a) 80; (b) $96
