Rael's freight forwarding company charges $14 for every vase delivered on time and $10 for every vase delivered late. In the month of October, Rael's freight forwarding company collected $920. For every 17 vases delivered, 15 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 Rael's freight forwarding company collect in October due to the late deliveries of the vases?

	On time	Late	Total
Number	15 u	2 u
Value	14	10
Total Value	210 u	20 u	230 u

(a)
Total amount collected in October
= 210 u + 20 u
= 230 u

230 u = 920

1 u = 920 ÷ 230 = 4

Total number of vases delivered on time
= 15 u
= 15 x 4
= 60

(b)
Amount that Rael's freight forwarding company collected less from each late delivery of vases
= 14 - 10
= $4

Number of vases delivered late
= 2 u 
= 2 x 4
= 8

Amount that Rael's freight forwarding company collected less from all the late deliveries of vases 
= 8 x 4
= $32

Answer(s): (a) 60; (b) $32
