\text{Ezra works two summer jobs to save for a laptop that costs at least }\$1100\\
\\
\text{also given that he charges 15 dollars per hour to mow lawns and }\\
\text{10 dollars per hour to walk dogs.}\\
\\
\text{so if he mow lawns for x hours and walk the dogs for y hours in summer,}\\
\text{then the inequality that modeles this data is}\\
\\
15x+10 y \geq 1100$

$\text{now suppose Ezra decides to also spend more than }\$80 \text{ on a printer,}\\
\text{so the total expences he want for laptop and printer is}=1100+80=1180\\
\\
\text{so now the inequality becomes: }$
