For this case we have the following data:

Available quantity: $ 24

Regular price: r

Sale price:[tex]r-5[/tex]

If we have that Roopesh can not pay more than $ 24, we can write the following inequality, taking into account that the item is sold in [tex]r-5[/tex]:

[tex]r-5 \leq24[/tex]

Clearing r:

[tex]r \leq24+5\\r \leq29[/tex]

Answer:

  • What is the unknown?

[tex]r \leq29[/tex]

  • Which expression can represent the sale price?

[tex]r-5[/tex]

  • Which comparison could be used?

The sale price decreases $ 5 and so the regular price is obtained.

  • The inequality is: [tex]r-5 \leq24[/tex]
