Hello,
So we can first assign HD videos and classic videos to specific variables, x is HD videos and y is classic videos.
Fiona bought 5 HD videos, and 2 classic videos for 31 dollars.
5x + 2y = 31
Iliana bought 3 HD videos and 5 classic videos for 30 dollars.
3x + 5y = 30
Therefore, the final answer is choice D, 5x + 2y = 31 and 3x + 5y = 30.
<u>Given </u><u>that</u><u> </u><u>:</u><u>-</u><u> </u>
<u>To</u><u> </u><u>Find</u><u> </u><u>:</u><u>-</u><u> </u>
<u>S</u><u>o</u><u>l</u><u>u</u><u>t</u><u>i</u><u>o</u><u>n</u><u> </u><u>:</u><u>-</u><u> </u>
<u>☆</u><u> </u>When a negative digit is multiplied with negative digit then the result comes as positive digit .
→ x × y = (-12)(-3)
→ x.y = 36
So the answer is 36.
