Step-by-step explanation:
When 2n is divided by 4 the remainder will be 2
Division is a simple operation in which a number is divided.
Given,
A whole number n which when divided by 4 gives 3 as remainder
We know,
Dividend = (Divisor × quotient)+ Remainder
Here,
Dividend = n
Quotient = 4
Remainder =3
Consider the divisor as a
Then,
n = 4a+3
Multiply both side by 2
2n= 2(4a+3)
2n= 8a+6
Split the term 6 and take common outside
2n= 8a+4+2
2n= 4(2a+1)+2
So, when 2n is divided by 4
Divisor = 2a+1
Remainder = 2
Hence, when 2n is divided by 4 the remainder will be 2

Given:
set-up fee 5,500
variable fee 1 per CD.
Cost per CD is $5.50
5.50 - 1= 4.50
5,500 / 4.50 = 1,222 CDs Choice A.
1*1,222 = 1,222
1,222 + 5,500 = 6,722
6,722/1,222 = 5.50
