1. Considering the definition of inequality, the number of friends admitted must be less than or equal to 12, expressed as p ≤ 12.

   What is inequality?

   ⇒ Inequality is the existing inequality between two algebraic expressions, connected through the signs:

   • greater than >.
   • less than <.
   • less than or equal to ≤.
   • greater than or equal to ≥.

   An inequality contains one or more unknown values ​​called unknowns, in addition to certain known data.

   Calculation:

   Solving an inequality consists of finding all the values ​​of the unknown for which the inequality relation holds.

   Inequality in this case

   In this case, you know that:

   • A group of friends has no more than $190 to spend on parking and admission.
   • Parking is $7
   • Tickets cost $15.25 per person, including tax.

   Being “p” the maximum number of people who can go to the amusement park, the inequality that expresses the previous relationship is

   15.25p + 7 ≤ 190

   On solving the inequality

   15.25p ≤ 190 -7

   15.25p ≤ 183

   p ≤ 183÷ 15.25

   ⇒ p ≤12

   ⇒ Finally, the number of friends admitted must be less than or equal to11, expressed as p ≤ 12
