Answer:
(a). 32 copies
(b). $3060
Step-by-step explanation:
<u>Solution for (a):</u>
<u />
P = 60c + 1800
If P is $3720 then;
3720 = 60c + 1800
60c = 3720 - 1800 = 1920
c =
= 32 copies
<u>Solution for (b):</u>
<u />
P = 60c + 1800
If c is 21 then;
P = $60(21) + $1800
P = $1260 + $1800
P = $3060
F: R → R is given by, f(x) = [x]
It is seen that f(1.2) = [1.2] = 1, f(1.9) = [1.9] = 1
So, f(1.2) = f(1.9), but 1.2 ≠ 1.9
f is not one-one
Now, consider 0.7 ε R
It is known that f(x) = [x] is always an integer. Thus, there does not exist any element x ε R such that f(x) = 0.7
So, f is not onto
Hence, the greatest integer function is neither one-one nor onto.
The answer was quite complicated but I hope it will help you.
