A blank CD can hold 70 minutes of music. So far you have burned 25 minutes of music onto the CD. You estimate that each song las

zaharov [31]

Answer:

The possible numbers of songs that you can burn onto the CD is 11.

Step-by-step explanation:

The total storage capacity of CD = 70 minutes

Storage already used = 25 minutes

Hence, The available storage = Total available storage - Used Storage

= 70 minutes - 25 minutes = 45 minutes

Hence, the CD has 45 minutes storage left.

Now, each song takes up 4 minutes of storage.

⇒ $\textrm{Total number of songs possible} = \frac{\textrm{Total storage left}}{\textrm{Time taken by each song}}$

= $\frac{45 minutes}{4minutes } = 11.25$

⇒The number of songs possible = 11.25 ≈ 11

Hence, the possible numbers of songs that you can burn onto the CD is 11.
