Answer:D 20%
Explanation:
To find the percentage of the cost of the CD relative to the total cost of the game and CD, we need to perform the following calculation:
(Cost of CD / Total cost) * 100%
Plugging in the given values, we get:
(15 / 75) * 100% = 20%.
Therefore, the cost of the CD is 20% of the total money spent on the game and CD.
