Question

Fiona and Iliana went to a going-out-of-business sale at a local video store. The store was advertizing all HD videos on sale for one price and all classic videos for a different price. Fiona bought 5 HD videos and 2 classic videos for $31. Iliana bought 5 classic videos and 3 HD videos for $30. Which system of equations can be used to find the prices of the classic and HD videos?

Answer 1

Correct answer on test is D. 5 x + 2 y = 31. 3 x + 5 y = 30.

Explanation:

Answer 2

5h + 2c = 31

5c + 3h = 30

Explanation:

Let h = HD video price

Let c = classic video price

Fiona bought 5 HD videos and 2 classic videos for $31

5h + 2c = 31

Iliana bought 5 classic videos and 3 HD videos for $30

5c + 3h = 30

This is the system of equations

5h + 2c = 31

5c + 3h = 30
