Let x represent the number of individual songs and y represent the number of albums, hence:

x + 8y ≤ 50   (1)

x ≤ 30    (2)

y > 2   (3)

The solution to the inequalities x + 8y ≤ 50, x ≤ 30, y > 2 is the darker region shown on the graph.

Answer:

$108

Step-by-step explanation:

From the above question, we have the proportion:

Company A/Company B

= $9/$2 = x/x24

The next step is : We Cross Multiply

2x = $24 × $9

x = $24 × $9/2

x = $108
