Question

Rogan is burning a music CD. The CD holds at most 70minutes of music. Rogan has already selected 45 minutesof music. Write and solve an inequality to find howmany more minutes of music Rogan can select.

Answer 1

Let x be more minutes of music that Rogan select.

The inequality for x is,

`x+45\leq70`

Simplify the inequality for x.

`\begin{gathered} x+45-45\leq70-45 \\ x\leq25 \end{gathered}`

The inequality is,

`x+45\leq70`

Rogan can select 25 more minutes of music.
