Question

Eliana takes photos and videos on her phone. Let P represent the number of photos and V represent the number of videos that Eliana can take using her storage space. 15P+70V < 400, Eliana wants to take 12 photos. How many videos at most can she take with the remaining storage space?

Answer 1

Answer:

She can take at most 3 videos.

Step-by-step explanation:

Here, P represent the number of photos and V represent the number of videos that Eliana can take using her storage space.

Also, the given inequality that shows this situation is,

$15P+70V < 400------(1)$

If Eliana wants to take 12 photos.

⇒ P = 12,

From inequality (1),

$15\times 12+70V$

$180+70V$

$70V$

$70V$

$V$

Since, the number of videos must be whole number,

Hence, the maximum number of videos she can take is 3. ( By the above inequality )

Answer 2

P = 12.

So,

15(12) + 70V < 400

V < (400 - 180)/17

V <3.14

So the max number of video can fit is 3.
