Jeremy's freight forwarding company charges $20 for picture frames delivered on time and $17 for picture frames delivered late. In the month of March, Jeremy's freight forwarding company collected $1392. For every 18 picture frames delivered, 14 were delivered on time and 4 were delivered late.

1. What was the total number of picture frames delivered late?
2. How much less money did Jeremy's freight forwarding company collect in March due to the late deliveries of the picture frames?

	On time	Late	Total
Number	14 u	4 u
Value	20	17
Total Value	280 u	68 u	348 u

(a)
Total amount collected in March
= 280 u + 68 u
= 348 u

348 u = 1392

1 u = 1392 ÷ 348 = 4

Total number of picture frames delivered late
= 4 u
= 4 x 4
= 16

(b)
Amount that Jeremy's freight forwarding company collected less from each late delivery of picture frames
= 20 - 17
= $3

Number of picture frames delivered late
= 4 u 
= 4 x 4
= 16

Amount that Jeremy's freight forwarding company collected less from all the late deliveries of picture frames 
= 16 x 3
= $48

Answer(s): (a) 16; (b) $48
