Tom's freight forwarding company charges $19 for every vase delivered on time and $17 for every vase delivered late. In the month of December, Tom's freight forwarding company collected $1792. For every 12 vases delivered, 10 were delivered on time and 2 were delivered late.

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

	On time	Late	Total
Number	10 u	2 u
Value	19	17
Total Value	190 u	34 u	224 u

(a)
Total amount collected in December
= 190 u + 34 u
= 224 u

224 u = 1792

1 u = 1792 ÷ 224 = 8

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

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

Number of vases delivered late
= 2 u 
= 2 x 8
= 16

Amount that Tom's freight forwarding company collected less from all the late deliveries of vases 
= 16 x 2
= $32

Answer(s): (a) 80; (b) $32
