Inequalities can you help me out?

Your answer is option A) Elaine can take at most 3 videos.

You can find this by substituting in 12 for the value of P into the equation 15P + 70V < 400

This gives you:
15(12) + 70V < 400
180 + 70V < 400
(- 180)
70V < 220
(÷ 70)
V < 3.14

From this you can see that the biggest integer V can be is 3, therefore the answer is A.

I hope this helps!

Ithink it’s b, hope this .
