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

2.) a(b+c)= ab + ac or a(b -c) = ab - ac
3.) equation containing more than one variable
4.) the number 1 (for the real numbers)
5.) <span>the reciprocal of a number; if x is a number other than zero, then 1/x is the multiplicative inverse

Each number in the code can be 1 of 10 numbers.
The total number of possible combinations is 10 * 10 * 10 * 10 = 10,000
The probability of getting 1234 would be 1/10,000
