Answer 1

D

Step-by-step explanation:

Answer 2

One correct inequality is

1.19x≤10,

and the correct solution is

x≤8.

Step-by-step explanation:

Let x be the number of songs Jose downloads. Each song has a cost of $1.19; this would give the total amount spent as 1.19*x, or 1.19x.

He has at most $10 to spend. This means he can spend less than $10 or exactly $10; this gives us the inequality symbol ≤, which makes our complete inequality

1.19x ≤ 10.

To solve this, divide both sides by 1.19:

1.19x/1.19 ≤ 10/1.19

x ≤ 8.4.

Jose won't download a partial song, so we round this down to 8:

x≤8
