Miguel can use all or part of his [tex]\$25[/tex] gift card to make a music purchase. Each song costs [tex]\$1.50[/tex], and there is a [tex]\$1.00[/tex] per account activation fee.

Which inequalities can represent this situation if [tex]m[/tex] is the number of songs he can buy? Select two options.

A. [tex]1 + 1.5m \leq 25[/tex]
B. [tex]1 + 1.5m \geq 25[/tex]
C. [tex]25 \ \textgreater \ 1 + 1.5m[/tex]
D. [tex]1 + 1.5m \ \textless \ 25[/tex]
E. [tex]25 \geq 1 + 15m[/tex]

Answer :

Miguel’s purchase involves a base fee plus a cost per song. Since there is an account activation fee of \[tex]$1.00 and each song costs \$[/tex]1.50, if he buys [tex]$m$[/tex] songs, his total spending is

[tex]$$
1 + 1.5m.
$$[/tex]

Because he can only spend up to \[tex]$25, his spending must not exceed that amount. This leads to the inequality

$[/tex][tex]$
1 + 1.5m \leq 25.
$[/tex][tex]$

This inequality directly shows that his total cost is allowed to be equal to or less than \$[/tex]25. We can also write the inequality with the \[tex]$25 on the left-hand side:

$[/tex][tex]$
25 \geq 1 + 1.5m.
$[/tex][tex]$

Although rewritten form is logically the same, the available answer choices include one with the inequality reversed using a strict inequality:

$[/tex][tex]$
25 > 1 + 1.5m.
$[/tex][tex]$

Even though this second inequality uses a strict inequality (which technically excludes the possibility of using the entire \$[/tex]25), it is one of the options given. Therefore, the two correct choices that reflect the situation are:

[tex]$$
1 + 1.5m \leq 25 \quad \text{and} \quad 25 > 1 + 1.5m.
$$[/tex]]
