Answer:
D. 3.99n < 50
Step-by-step explanation:
We know each movie costs 3.99, and Parv has a $50 gift card. So we know at most, Parv can spend $50. This quickly eliminates A, B, and C, and leaves D as our answer.
3.99n ≤ 50
Divide both sides by 3.99
n ≤ 50/3.99
n ≤ 12.53
n ≤ 12
Parv can buy at most 12 movies.
I solved the inequality because it was a pretty short explanation. Anyway, I hope this helps! ^w^
