Question

Henry purchased compact disks for $112. The compact discs cost $16 each.

Which of the following equations could you use to find how many compact disks, x, Henry purchased?

$112 = x - $16
$112 = $16 x
$16 = $112 x
$112 = x/16

Answer 1

To find how many compact disks, \( x \), Henry purchased at a cost of $16 each and a total expenditure of $112, you can set up the equation based on the total cost being equal to the number of disks multiplied by the cost per disk.

The appropriate equation is:

\[
112 = 16x
\]

This equation states that the total cost of $112 is equal to the number of compact disks \( x \) times their price per disk ($16).

So, the correct option is:

\[
112 = 16x
\]
