Judy bought 6 CDs priced at $12 each. She paid for $10 of the price, then split the rest between five of her friends,
a. Write an expression to describe how much each of her friends paid
b. Evaluate your expression to calculate how much each friend paid.

a. if x equals the price that one of the five friends paid, then the formula

x= (6*12-10)/5 should represent the price each friend paid

b. evaluating this, x = 12.4

Step-by-step explanation: The price of the total cost of all 6 CDs is 6*12, or 72.  Since she paid $10, the remaining price is $62, and if this price is split between 5 friends, the price each friend paid in 62/5, or 12.4.  Simply put this into a equation, and you'll find the equation.  Simplifying the equation itself only requires for you to follow PEMDAS (or GEMDAS), which are acronyms for the orders of operation.
