But negation contains only opposite of given statement.
So, Some students in my class do not use e-mail” is not true.
V = 4/3 * (pi) * r^3
V = 4/3 * (pi) * 10^3
V = 4/3 * (pi) * 1000
V = 4000/3(pi)
V = 1333 1/3 (pi) in^3 <==
Let's assume
total number of cards =x
Pristine printing business cards:
for $0.10 each plus a setup charge of $15
so, we get equation for cost as
Printing Place business cards:
for $0.15 each with a setup charge of $10

so, we can set costs equal
now, we can solve for x
so,
number of business cards is 100.........Answer
