<h3><u>The system of linear inequalities to model the situation are:</u></h3>
<em><u>Solution:</u></em>
Let "x" be the time spent in dog walking job
Let "y" be the time spent in car wash attendant
Given that,
<em><u>You can work at most 20 hours next week</u></em>
"at most" means "less than or equal to" 20
Therefore,
Also given that,
Your dog- walking job pays $7.50 per hour
Your job as a car wash attendant pays $6 per hour
<em><u>You need to earn at least $92 to cover you weekly expenses</u></em>
"at least" means "greater than or equal to" 92
Thus, a inequality is framed as:
Thus eqn 1 and eqn 2 is the system of linear inequalities to model the situation
