Given an inequalities below:
[tex]1.5+2.1y<1.1y+4.5[/tex]The inequalities can be solved by collecting like terms and evalauating the unknown
[tex]1.5+2.1y<1.1y+4.5[/tex][tex]\begin{gathered} 1.5+2.1y<1.1y+4.5 \\ \text{collect like terms} \\ 2.1y-1.1y<4.5-1.5 \\ 1y<3 \\ \text{divide both side by 1} \\ y<3 \end{gathered}[/tex]Hence the correct answer is
[tex]y<3[/tex]
