To find the price of the triple pack, we can set up an equation where x represents the cost of the triple pack. The equation based on the information given is:
0.75x - 4 = 20
Now, to solve for x, add 4 to both sides of the equation:
0.75x = 24
Then, divide both sides by 0.75 to find the price of the triple pack:
x = 24 / 0.75
x = 32
Therefore, the price of a triple pack of CD's is $32.
The price of a triple pack of CDs is $32, determined by solving the equation based on the cost of a double pack and its relation to the triple pack's price.
