Justin's freight forwarding company charges $15 for every vase delivered on time and $13 for every vase delivered late. In the month of September, Justin's freight forwarding company collected $1616. For every 14 vases delivered, 10 were delivered on time and 4 were delivered late.

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

	On time	Late	Total
Number	10 u	4 u
Value	15	13
Total Value	150 u	52 u	202 u

(a)
Total amount collected in September
= 150 u + 52 u
= 202 u

202 u = 1616

1 u = 1616 ÷ 202 = 8

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

(b)
Amount that Justin's freight forwarding company collected less from each late delivery of vases
= 15 - 13
= $2

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

Amount that Justin's freight forwarding company collected less from all the late deliveries of vases 
= 32 x 2
= $64

Answer(s): (a) 80; (b) $64
