11) For most products… d=800-10p
a) d=800-10(20)=600, d=800-10(70)= 100
b) d=800-10(26)=540, d=800-10(27)=260, d=800-10(68)=120, d=800-10(69)=110
c) TR=d*p, TR=800-10(p)
d) 800-10p^2, 800(30)-10(30)^2= 15000, 800(40)-10(40)^2= 16000, 800(50)-10(50)^2=15000
e) TR/p=d*p/p, d=tr/p, d=16000/40= 400 units
13) Micromedia offers…
a) 9600+120x
b) p=600x-(9600+120x)=480x-9600
c) 480(30)-9600=4800
d) p=480x-9600=0, x=20 students

Regular inflected forms are not included; their meanings are predictable given English morphology.

Change of Meaning: Causes, Nature, and Results
In the course of the development of the language, a great number of words change their meanings. There are some factors that bring about this semantic change. They are divided into two groups: linguistic causes and extra-linguistic causes.
Linguistic Causes
The first group includes changes related to linguistic causes. The most common form of these changes is ellipsis. In this case, a phrase made up of two words omits one of them, and its meaning is transferred
