Answer:

$10n \le 30$

$n \le 3$

Explanation:

Given

$Total = \$30$

$Cost (each) = \$10$

Required

Determine the inequality

Assume she wants to buy n CDs.

If 1 CD costs $10, then n CDs costs 10n.

So, the inequality is:

$10n \le 30$

We used
$\le$ because the amount she wants to spend cannot exceed 30

Divide both sides by 10, to solve for n

$n \le 3$
