Question

A local store’s clearance rack is full of DVDs selling for $8 each and CDs selling for $6 each. Let x represent the number of DVDs, and let y represent the number of CDs. Which inequality can be used to find combinations of DVDs and CDs that can be bought with a $50 gift card?

Answer 1

A 8x + 6y is less than or equal to 50

Explanation:

took the test

Answer 2

`8x+6y\leq 50`

Explanation:

Let

x------> the number of DVDs

y------> the number of CDs

we know that

`8x+6y\leq 50` -------> inequality that represent the situation

The solution is the shaded area below the solid line between the positive values of x and y

The equation of the line is
`8x+6y=50`

The slope of the line is negative

The y-intercept of the line is the point
`(0,8.33)`

The x-intercept of the line is the point
`(6.25,0)`

The solution is the triangular area in the attached figure
