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.

Evaluate the series 4 – 2 + 1 – 0.5 + 0.25 to S10. Round to the nearest hundredth.

aleksklad [387]

The initial term of this geometric series is 4, and the common ratio is -1/2. The sum is given by

$S_{n}=a_{1}\dfrac{r^{n}-1}{r-1}\\\\S_{10}=4\cdot \dfrac{(-\frac{1}{2})^{10}-1}{-\frac{1}{2}-1}=4\cdot \dfrac{(\frac{1}{1024}-1)}{(-\frac{3}{2})}\\\\=\dfrac{8}{3}\cdot \dfrac{1023}{1024}=\dfrac{341}{128}$

The sum is approximately 2.66.
