The system of inequalities that Jeff can use to find the number of tickets he can buy is A. x + y ≥ 8 and 300 ≥ 15x + 30y
What is system of inequalities ?
A collection of two or more inequality in one or more variables is called a system of inequality. When there are multiple constraints on a problem's possible solutions, systems of inequalities are employed to find a solution.
Based on the provided information,
He wants tickets for at least 8 concerts which means ≥
let x =ticket for an afternoon concert costs =$15
Let y=ticket for an evening concert costs= $30
Then we have
x + y ≥ 8
Jeff wants to spend no more than $300. ≤
15x + 30y≤ $300
300 ≥ 15x + 30y
Then the two equations are
x + y ≥ 8
300 ≥ 15x + 30y
