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,
[tex]15P+70V < 400------(1)[/tex]
If Eliana wants to take 12 photos.
⇒ P = 12,
From inequality (1),
[tex]15\times 12+70V<400[/tex]
[tex]180+70V<400[/tex]
[tex]70V<400-180[/tex]
[tex]70V<220[/tex]
[tex]V<\frac{22}{7}\approx 3.14[/tex]
Since, the number of videos must be whole number,
Hence, the maximum number of videos she can take is 3. ( By the above inequality )
The number of videos she can take with the remaining storage space is less than 4
Given the inequality expression representing the storage space as
15P+70V < 400
where:
Given P = 12, the expression becomes;
15(12)+70V < 400
180 + 70 V < 400
70V < 400 - 120
70V < 280
V < 4
Hence the number of videos she can take with the remaining storage space is less than 4
