Neave's freight forwarding company charges $19 for every mirror delivered on time and $17 for every mirror delivered late. In the month of April, Neave's freight forwarding company collected $3069. For every 15 mirrors delivered, 12 were delivered on time and 3 were delivered late.

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

	On time	Late	Total
Number	12 u	3 u
Value	19	17
Total Value	228 u	51 u	279 u

(a)
Total amount collected in April
= 228 u + 51 u
= 279 u

279 u = 3069

1 u = 3069 ÷ 279 = 11

Total number of mirrors delivered on time
= 12 u
= 12 x 11
= 132

(b)
Amount that Neave's freight forwarding company collected less from each late delivery of mirrors
= 19 - 17
= $2

Number of mirrors delivered late
= 3 u 
= 3 x 11
= 33

Amount that Neave's freight forwarding company collected less from all the late deliveries of mirrors 
= 33 x 2
= $66

Answer(s): (a) 132; (b) $66
