Harry's freight forwarding company charges $20 for crystal bowls delivered on time and $17 for crystal bowls delivered late. In the month of October, Harry's freight forwarding company collected $2156. For every 16 crystal bowls delivered, 12 were delivered on time and 4 were delivered late.

1. What was the total number of crystal bowls delivered late?
2. How much less money did Harry's freight forwarding company collect in October due to the late deliveries of the crystal bowls?

	On time	Late	Total
Number	12 u	4 u
Value	20	17
Total Value	240 u	68 u	308 u

(a)
Total amount collected in October
= 240 u + 68 u
= 308 u

308 u = 2156

1 u = 2156 ÷ 308 = 7

Total number of crystal bowls delivered late
= 4 u
= 4 x 7
= 28

(b)
Amount that Harry's freight forwarding company collected less from each late delivery of crystal bowls
= 20 - 17
= $3

Number of crystal bowls delivered late
= 4 u 
= 4 x 7
= 28

Amount that Harry's freight forwarding company collected less from all the late deliveries of crystal bowls 
= 28 x 3
= $84

Answer(s): (a) 28; (b) $84
