Bobby's freight forwarding company charges $13 for crystal bowls delivered on time and $10 for crystal bowls delivered late. In the month of May, Bobby's freight forwarding company collected $2540. For every 20 crystal bowls delivered, 18 were delivered on time and 2 were delivered late.

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

	On time	Late	Total
Number	18 u	2 u
Value	13	10
Total Value	234 u	20 u	254 u

(a)
Total amount collected in May
= 234 u + 20 u
= 254 u

254 u = 2540

1 u = 2540 ÷ 254 = 10

Total number of crystal bowls delivered late
= 2 u
= 2 x 10
= 20

(b)
Amount that Bobby's freight forwarding company collected less from each late delivery of crystal bowls
= 13 - 10
= $3

Number of crystal bowls delivered late
= 2 u 
= 2 x 10
= 20

Amount that Bobby's freight forwarding company collected less from all the late deliveries of crystal bowls 
= 20 x 3
= $60

Answer(s): (a) 20; (b) $60
