Tommy's freight forwarding company charges $12 for every vase delivered on time and $10 for every vase delivered late. In the month of November, Tommy's freight forwarding company collected $1936. For every 15 vases delivered, 13 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 Tommy's freight forwarding company collect in November due to the late deliveries of the vases?

	On time	Late	Total
Number	13 u	2 u
Value	12	10
Total Value	156 u	20 u	176 u

(a)
Total amount collected in November
= 156 u + 20 u
= 176 u

176 u = 1936

1 u = 1936 ÷ 176 = 11

Total number of vases delivered on time
= 13 u
= 13 x 11
= 143

(b)
Amount that Tommy's freight forwarding company collected less from each late delivery of vases
= 12 - 10
= $2

Number of vases delivered late
= 2 u 
= 2 x 11
= 22

Amount that Tommy's freight forwarding company collected less from all the late deliveries of vases 
= 22 x 2
= $44

Answer(s): (a) 143; (b) $44
